When looking for shared accommodation, people often use an online platform without really questioning how it works. However, not all digital platforms provide the same service. Some connect individuals, others sell a product directly, and still others organize content for millions of users. Understanding these differences helps in better choosing the right tool for one’s needs.
Transparency obligations imposed by the DSA on online platforms
Since February 17, 2024, the Digital Services Act (DSA) has redefined what is expected from a digital platform in Europe. This regulation distinguishes several levels of intermediary services and applies obligations proportional to their size and role.
Very large online platforms and very large search engines must now publish a moderation report every six months. This report details the content removed, the decisions made, and the systemic risks identified, particularly for minors and mental health.
Specifically, a hosting service (including a community platform) must inform each user when content is removed or made inaccessible. The justification must mention the legal or contractual rule invoked. This obligation clearly distinguishes a content platform from a simple web application that disseminates information without interaction.
The DSA also requires very large platforms to offer a recommendation system not based on profiling. Users must be able to choose an alternative to personalized algorithmic sorting. Have you noticed the “chronological feed” option on some social networks? This is a direct consequence of this requirement.
Knowing the different types of platforms helps to understand why these obligations do not apply in the same way to a marketplace, a social network, or a cloud service.
Marketplace, SaaS, and content platform: three distinct logics
Grouping all platforms under the same label would be misleading. Their operation, business model, and regulatory constraints vary greatly depending on their type.
Marketplace: connecting parties as the central value
A marketplace connects sellers and buyers (or service providers and clients) without owning the product or service exchanged. Think of a housing reservation platform or a resale site between individuals.
The marketplace derives its value from the volume of offers and active users. The broader the catalog, the more reasons the buyer has to return. The model generally relies on a commission taken from each transaction.
In terms of data, the marketplace collects information about both parties: contact details, purchase history, reviews. The DSA requires it to verify the identity of professional sellers and to allow users to easily report illegal content.
SaaS platform: the tool as a product
Software as a Service (SaaS) operates differently. The user pays a subscription to access a tool hosted in the cloud: project management, accounting, professional messaging. There is no connection between third parties.
The SaaS sells a functionality, not an audience. Its value lies in technical reliability, data security, and the ability to integrate with other services. Regulatory obligations are more related to GDPR than to DSA, as the platform processes customer data without hosting public content.
Content platforms and social networks
Content platforms (video, articles, podcasts) and social networks constitute a third category. Their model relies on user attention, monetized through targeted advertising.
It is on this type of platform that the DSA obligations are the most stringent. Active moderation, algorithmic transparency, protection of minors: every decision to remove or promote content must be justifiable and contestable by the concerned user.
Concrete criteria for choosing a suitable digital platform
Why does this choice deserve so much attention? Because an unsuitable platform wastes time, money, and sometimes personal data. Here are the criteria that allow for effective sorting.
- The role of the platform in the transaction. If it connects two parties, check that it provides a minimum level of mediation (customer service, dispute resolution, profile verification). A marketplace without a safety net exposes both the seller and the buyer.
- The data and moderation policy. Since the DSA, online platforms must publish their moderation rules and justify each content removal. A platform that does not do this likely does not comply with its European obligations.
- The business model. Commission per transaction, monthly subscription, advertising, or freemium? The model determines how the platform treats its users. A free service funded by advertising tends to increase the time spent online, not the quality of the experience.
- Technical interoperability. For a business, a platform’s ability to connect with other tools (APIs, data exports, integrations) determines its long-term usefulness. A closed tool creates a dependency that is hard to break.
Collaborative platforms and the sharing economy: a special case
Collaborative platforms deserve specific mention. They borrow from the marketplace the principle of connecting parties, but the usage framework differs. Services (carpooling, temporary accommodation, shared housing) are exchanged rather than goods.
Their uniqueness lies in the trust relationship between users. Review systems, identity verification, and integrated messaging play a central role. Without trust between peers, the collaborative platform loses its purpose.
The regulatory framework for these platforms is evolving rapidly. In addition to the DSA, some must report their users’ income to tax authorities. This obligation concerns platforms facilitating transactions between individuals beyond certain thresholds.
Each type of platform responds to its own logic, with its technical, economic, and legal constraints. The most useful approach is to start from one’s real need (selling, collaborating, disseminating, managing) and to verify that the chosen platform complies with the obligations applicable to its category.
