Oh not that I have a side, I don't really understand what's at stake here anyway, it just seems that 2 teams are fighting like hell each of them trying to keep control over the blockchain xD
What you wrote is complete nonsense. Bitcoin Core is not fighting anything nor anyone. They don't even want any kind of control, i.e. they do not attempt to force any consensus change. On the other hand, BU is trying to force an unwanted HF.
Disagreed:
You got one side trying to force HF. You got one side trying to stop it.
Pretty fair to say that both sides are trying to keep control on the blockchain...
Though I do agree that "control" was maybe not the right word because it could refer to actively being able to change the blockchain at will which is not what I wanted to say.
