This feels more like a gradual tightening of extension APIs under Manifest V3 than a sudden “kill switch.” uBlock isn’t going away, but its capabilities are definitely being reshaped...

Sadly I don't think that's the general case, I've been on FF for decades but there isn't a universe where I use a browser without UBO at this point.
One wouldn't need to be loyal to UBO... a simple with-and-without comparison would be enough for anyone with a functioning brainstem.
