It's much easier to criticize than to build an alternative. I don't think anyone at Metamask or in the space in general thinks to themselves that the ecosystem is in a state of full maturity or that there aren't major problems. Despite its shortcomings, MM and Web3 have given us capabilities that simply didn't exist five years ago. And those capabilities aren't just limited to a select number of shadowy super hackers. MM has millions of MAU and that number will only grow as more people see the potential of the tech.
