So now the maintainer must follow the order of the crow. What if the proposals are not in the maintainer vision or just bad? Can s/he fork the project? Is the DAO going to sue?

It looks like an idea for one time funding. That pays the bills the first years luckily. The second year the 90% of the users will be already in the DAO. Is everyone going to pay again? Are the new 10% going to pay more to compensate the small number? Are the new shares proportional to the money?
