Recital 15

The fact that a digital service qualifies as a core platform service does not in itself give rise to sufficiently serious concerns of contestability or unfair practices. It is only when a core platform service constitutes an important gateway and is operated by an undertaking with a significant impact in the internal market and an entrenched and durable position, or by an undertaking that will foreseeably enjoy such a position in the near future, that such concerns arise. Accordingly, the targeted set of harmonised rules in this Regulation should apply only to undertakings designated on the basis of those three objective criteria, and they should only apply to those of their core platform services that individually constitute an important gateway for business users to reach end users. The fact that it is possible that an undertaking providing core platform services not only intermediates between business users and end users, but also between end users and end users, for example in the case of number-independent interpersonal communications services, should not preclude the conclusion that such an undertaking is or could be an important gateway for business users to reach end users.
