> As a weird sidenote to this: Whilst I was looking up the benchmarks of the iPhone I found out that basically every single tech mag is owned by the exact same company - you can tell because they all have the same adblocker nagware.

This nagware is available as a service now (CMP, short for "Consent Management Provider/Platform"). Popular examples (out of what I remember from an evaluation some time ago) are TrustArc (used e.g. by Oracle), consentmanager.de (lots of German media) and Usercentrics.
