The central role digital platforms play in economic relations and their potential impact in democratic processes and human rights require adequate regulation to optimize how society uses them. One important regulatory step is implementing platform interoperability - which has many facets, from data to protocols and legal systems. This potentially unlocks value in digital environments, strengthening competition and providing user control.

This session of the DCNN meeting highlighted the various aspects of internet openness that go beyond the usual debate on net neutrality. These include device neutrality and interoperability, which were the focus of the session due to their key role in a more open and multi-faceted debate about internet openness.

Classical net neutrality issues, such as non-discriminatory packet management, are necessary, albeit not sufficient to achieve the ideal of internet openness proposed. Increasingly, net neutrality issues take the fore alongside these other debates, revealing the need for a multi-layered approach to internet openness.

ARCEP, the French telecommunications regulator, has given substance to this in a recent study on Device Neutrality and their impact on consumers. Among their findings, some highlights are: (i) limitations in terms of consumer experiences; (ii) limitations in terms of application providers’ ability to offer services via marketplaces; and (iii) unequal implementation of web standards; among other barriers to competition and openness in the market that end up harming user experience and access to the internet as a whole. Some policy options to face these challenges would be provisions for more transparency for entry conditions in OS marketplaces and increased API transparency, as well as advocating for interoperability of various services.

In terms of interoperability, it is important to understand that its role as an enabler of an open internet is due to its potential to unravel lock-in and network effects and create connections where otherwise there would be barriers. The concept may be divided into two categories: (i) vertical interoperability, when an app can access various platforms and an user can interact with users from other platforms; and (ii) horizontal interoperability: provides inter-platform competition, enabling competition among different marketplaces. Both are necessary to promote internet openness.

In order to achieve this, regulators would need to require platforms characterized as “gatekeepers” to open up to competitors - whether by APIs, standard communication protocols like the WWW consortium etc. This would not be unheard of, as some countries have already instituted interoperability requirements in the case of open banking schemes, which allowed fintech companies to enter markets, increasing competition and giving consumers a genuine choice.

This amplification of choice is reflected in more options, for example, in terms of privacy choices and content moderation choices. Further social benefits of interoperability include promoting media pluralism and diversity, improved social infrastructure, reduced environmental impact of the online economy and the Internet of Things, and favoring digital sovereignty. This impact is made very clear by moments of crisis: in recent controversies over privacy policies of popular messaging apps, peoples whose internet packages include zero-rated connectivity for incumbent apps might feel powerless to question privacy practices and be incapable of swapping services due to potential internet costs.

Although these are recognized beneficial effects of interoperability and net neutrality which make up a more open internet as a whole, there are still many challenges and drawbacks in their implementation, including particular issues in countries where regulation of net neutrality is lax or uncertain.
