Feels like a mob boss sending a message. "We own this platform, we make the rules, and we don't care who you are or how big you are, you mess with us we'll terminate your account and revenue stream." C'mon EU, do something.
We own this platform, (we built this platform), we make the rules I don't see the issue with this... it's not like they're exploiting an inherited platform like Oracle with (everything), IBM with Red Hat or Broadcom with VMware.
At least Microsoft had no way of stopping you selling apps for Windows but Apple is a next level of nefarious.
