Very valid points! I can make a few promises: although the Manyverse open collective may be related to crypto for funding, Manyverse as an app will never have any blockchain integration or in-app purchases. We make some strong promises on our website and we'll keep those promises.
In the recent past I've been vocal against crypto projects. I don't intend to change that.
That said, I think it's more productive to have "one enemy", to criticize one thing and to focus my energies on work against that enemy. Having multiple enemies, criticizing many things at once, is too puritan and leads to very little energy towards any one thing. For instance, I could criticize and be against GitHub, but doing so would demand more energy from me, migrating away from it, not interacting with it. The net effect is a visible reduction in productivity.
So I make a compromise on that, I use GitHub and crypto and other "evils" while focusing my energy on fighting against one thing: centralized social networks.
