No, I didn't say that.

The whole point of DRM is to attest to the provider that the content is
being consumed by a player with certain properties (specifically
robustness). Those properties obviously vary by platform, so yes, all DRM
gives the provider some control over which players on which platforms can
play the content. Specifically, to ensure the player has the robustness
properties required by the content license.

I don't see what EME has to do with this point. It is just a well-known
property of DRM independent of whether the DRM is accessed through EME or
some other way.
