A few simple points:
1) Even if it does happen, it wont be Bitcoin, so it wont matter.
A fork of Bitcoin is not Bitcoin.
Bitcoin works no matter what the price, and even a large drop in hash rate has no real effect on that - as expected, and as we saw, when china shutdown mining.
2) The magic 51% number rears it's head yet again
Pools mining against lower points in the active chain will be obvious.
So it would become immediately clear what pools not to mine on.
Excluding higher paying transactions means less mining reward in your block.
Excluding the lowest paying transactions, when block space is at a premium, is how Bitcoin works.
Messing with that means less bitcoin reward for mining.
(Which is what StratumV2 is trying to make happen - stay away from V2 - they're probably backed by the gov't since they are helping to do this)
3) It's the current us gov't that's trying to damage Bitcoin, not sure why anyone in Bitcoin would want to keep them in power
lol
Im not into politics but it evident now that whoever is from the US and supports bitcoin while voting for Biden has some sort of massive cognitive dissonance of Stockholm syndrome going on, otherwise I don't get it. This people have a clear agenda to tie Bitcoin and crypto as something that funds terrorism and "white supremacy" while forgetting about how everyone that lives in countries where inflation is making everyone poor uses BTC to survive. They don't care, they are mad that people got rich from getting in early and they didn't, so now they want to ban it.
If anyone wants BTC to survive at a mainstream level, then pro-Bitcoin lobbying is non negotiable. We need people supporting BTC and miners at the political level, otherwise we are going to see Biden, Warren, AOC and co make Bitcoin unusable for US citizens and miners kicked out of the country, again, at a mainstream level. Obviously BTC will survive no matter what, but if we want huge valuations, we need institutional support. The ETFs are a good step in this direction, but don't forget that the ETFs can be used against self-sovereign BTC users that do self-custody, since they can concentrate the funds there then ban BTC from the hands of individuals. Stay alert because that is coming. It just happened in the EU.
