I don't think anyone would be pissed at projects that ask to get paid upfront. When you provide a product for free, then switch the features to a paid model, it's normal that people will talk about it and won't be super happy about the situation. Sure they aren't entitled to anything, but maintainers aren't entitled to a criticism-free discussion of their project just because the project is open source (in part) either.

Oh don't worry, it's made it much less likely that I never develop in the open ever again
