As with all changes at large tech companies, this change is being rolled out to a subsection of the whole userbase. As such, if you're not seeing it yet, it might be because you just haven't gotten into the rollout yet.
Or Firefox and uBlock are still managing to beat the countermeasures, who knows.
It's how you boil a frog. They're not gonna back down off of this. They decided a long time ago to maximize profitability at the cost of service degradation.
Rollouts are not made to boil frogs, they are made so that you can test the impact of changes, and crucially, quickly roll undesired changes back. It's a great technique. This is important when you're at Google-scale - any small mistakes will impact millions of people. The only realistic way to handle this is to roll changes out and monitor the changes for negative impacts - stuff like crashes and so on.
I agree that what they're doing is boiling the frog, but rollouts have nothing to do with it.
