Even if we most Bitcoiners won't like it, myself included, I would still prefer that people use good custodial service than not using Bitcoin at all. Most of Bitcoiner didn't jump to non-custodial wallet and running a node in the first year if not several years of using/experimenting with Bitcoin. 

Most user need to easily buy some sats from their Revolut, trading app or whatever, see the price moving up and down, get used to the terms and how to send and receive, buy some stuff, then maybe they will buy more, start to thing about security, independance, ... and will decide for a better solution, test it, get confortable, move a bit of sats, then more, evetually almost all beside daily spending sats stack.

I think it's fine and even if some will always stick with custodial, as long as we all have the possibilty to do self-custodial without any restriction, interact with any custodial service without whitlisting address and shit, I'm fine with it.
