There’s a lack of charity in general because the thinking is that the Monero project is a detraction from the advocacy and development that needs to be taking place on the Bitcoin protocol, the protocol that’s truly fixing money.

It's undeserved lack of charity. Bitcoiners take anything not bitcoin as an attack on them even when goals are different.
If Bitcoin focused on privacy and fungibility there would be no need for Monero and it wouldn't exist. So this is the outcome. Then maxis get upset when it is built into another crypto that focuses on these goals specifically. Bitcoin purported solutions are always half-solutions. If bitcoin tries doing everything well, it will do nothing well.
Like I said, if bitcoin figures out how to do it better, I will use it.
