I don't really buy that argument. I'm against Segwit2x, but nobody has ownership of the name. I think attempts to own the name "Bitcoin" (in the sense of intellectual property) goes against what Bitcoin stands for, as the enforcement of IP requires centralized authority and state intervention. It creates confusion for newbies, true. But I don't think that qualifies as an attack. I'm okay with the idea of openly competing forks.
But I agree with those who think that miner coordination adds an element of coercion, since 1) users fear being on the weaker chain and 2) users need confirmations. Miners leveraging these fears and economic needs can be seen as an attack.
Well nobody has ownership in name of BTC, they do not have copyright ok but BTC belongs who develops it, so the actual BTC.
If you have enough power mining you can then take away the name of any altcoin for example and keep it for yourself?
I understand what do you mean but in somehow they "own it", the community own it. It is an open source project and anyone who want to contribute can do it, so just appropiate the name to someone else work does not makes sense. Well it makes sense for them as they "steal" something that already works.
I can give many examples but just got in mind even it is not the same topic but can be something similar when BCH forks and they copy Electrum wallet for BCH (finally they change the name to Electron). Electrum does not care they copy the code but to appropiate of their name it is not honest at all.
