We've seen Zuckerburg pivot from openly pledging to defy the EU [1] and then presenting compliant plans six months later to avoid the the periodic fine [2].
But we've also seen Apple in a bid to avoid the periodic fine imposing a ~20% commission [3] on third party payments after their 27% fee was ruled illegal and they were told it must be free [4]. The investigation into that has taken a year now despite being immediately perceived as noncompliant by many developers and ressembling what Google was recently fined €430 million for [5] and Apple seems to feel no pressure to change it.
I guess what happens next to Apple will decide if companies fear this regulation, the periodic fine they were due if they didn't drop the 27% fee was touted to be up to $50m/day retroactively for the entire noncompliance period, which is now at least 400 days so lots of opportunity to send a message.
