Restrictions on end users’ ability to install and use third party software*

The rules that a gatekeeper sets for the distribution of software applications can, in certain circumstances, restrict the ability of end users to install and effectively use third-party software applications or software application stores on hardware or operating systems of that gatekeeper and restrict the ability of end users to access such software applications or software application stores outside the core platform services of that gatekeeper. Such restrictions can limit the ability of developers of software applications to use alternative distribution channels and the ability of end users to choose between different software applications from different distribution channels and should be prohibited as unfair and liable to weaken the contestability of core platform services. To ensure contestability, the gatekeeper should furthermore allow the third-party software applications or software application stores to prompt the end user to decide whether that service should become the default and enable that change to be carried out easily.

In order to ensure that third-party software applications or software application stores do not endanger the integrity of the hardware or operating system provided by the gatekeeper, it should be possible for the gatekeeper concerned to implement proportionate technical or contractual measures to achieve that goal if the gatekeeper demonstrates that such measures are necessary and justified and that there are no less-restrictive means to safeguard the integrity of the hardware or operating system. The integrity of the hardware or the operating system should include any design options that need to be implemented and maintained in order for the hardware or the operating system to be protected against unauthorised access, by ensuring that security controls specified for the hardware or the operating system concerned cannot be compromised. Furthermore, in order to ensure that third-party software applications or software application stores do not undermine end users’ security, it should be possible for the gatekeeper to implement strictly necessary and proportionate measures and settings, other than default settings, enabling end users to effectively protect security in relation to third-party software applications or software application stores if the gatekeeper demonstrates that such measures and settings are strictly necessary and justified and that there are no less-restrictive means to achieve that goal. The gatekeeper should be prevented from implementing such measures as a default setting or as pre-installation.
