They can call their forked coin "Bitcoin" if they want but it's not going to catch on. It's fundamentally different than Bitcoin and all these people want is control.
This. They have been trying to control BTC industry on several occasions now, it s mostly related to Chinese mining farms who were behind SegWit2x. Guess what, they have failed and they will FAIL again.
The problem is they make a lot of money in these attempts cause poor unsuspecting noobs always get caught into their net.
So to answer your question, NO, you should not be bothered.
