The Leader of Bitcoin is the Bitcoin Dev Team : Blockstream
Nope. Again, there's no leader in bitcoin and by that I mean an entity that affects it in such an intensive way, that if Blockstream moved to another cryptocurrency, the bitcoin community would follow likewise. This kind of leadership exists in Ethereum for example, where Vitalik decided that the community should abandon Ethereum Classic's chain and most of them did.
Bitcoin suffers
the least from this type of weakness due to its significant ideology.

I've seen enough in this forum alone to know not everyone's a Blockstream fanboy, and enough in outside sources to know Blockstream fans aren't actually really Bitcoin users themselves.
For example, sure, I thought ther satellite service was cool at some point but no Lightning user I know (yeah I don't know many) flocked to Blockstream's iteration.
And they know full well too they don't wield the same influence Ethereum's core dev did (do). Only need to look back to 2017 to see what happens when someone or a group of powerful people believe they could convince the community of users to go one way and one way only.
