Yes the op return limit was not formally protocol, but the filter was mostly enforced as law, and the point is the change of opinion did not make any sense. Don't you see a red flag there?
Some people did care, and complained. They were ignored. Weren't they? Another red flag. Most people do not really have the time to stay on things, informed and all that, so you can't judge silence as rejection or apathy.
Core devs behaved as they were running the show unilaterally.
I do not see why miners would have to "go
In line" once they agree to collude. The hope was they will chose safety, and thus could have been backed by promises of fiat bailouts behind the scenes. It is a possibility.
For whatever reason a most hostile was decided? Who was doing anything about it? Even the 20% knots market share jump in matter of weeks was impressive, but insufficient to improve things.
Anyway, decentralization means you have the right to think you hold the truth and stay on the legacy chain. If you are indeed right, things will go well for you and you'll have nothing to worry about.
But if you find later you were wrong, and the legacy chain is indeed captured, you will be be thankful we forked now so you have a non captured coin to move to. And the earlier you notice that, the more you will be rewarded.
