From the way this article reads Zuck is being derided specifically for getting caught.
That's certainly true. But this is Cory Doctorow who invented the concept of enshittification. I'd be super surprised if he thought anti-competetive behaviour is fine as long as you get away with it. My take is that he's saying "Not only is Zuckerberg a greedy asshole, but he's even stupid enough to make it provable in court."
Probably with some shades of 'shameless' / "everybody I know is doing it, and if it's normal it can't be illegal" too.
It shows a certain arrogance.
Some kind of too big to fail
I agree, I got the same impression when I was reading the article.
