Google can push back, US companies can do that, and do do that. That system isn't perfect but I'd rather go with apps from more free countries than those that are not free.
It's unclear to what extent such corporate pushback against the USG is genuine conflict as opposed to theater/PR cover. I don't think it's a safe assumption either way. The incentives to pretend industry has more independence than it does are there, and methods of such deception have been seen before.
I think it is unlikely we have a conspiracy so vast, across a ton of companies that they put up fake legal fights, have fake warrant canary notices ... and nobody ever leaks out that they're all fake.
There doesn't need to be any conspiracy. If it's good for PR reasons to show they are fighting, companies will do it anyway without the need to coordinate.
ByteDance has no choice.
