That response is quite…hostile?

Someone spent their time to report a bug they found but close it because they didn’t pay the dev? Isn’t that a kind of contribution?

It is totally acceptable to ignore it but closing the issue with hostility is a questionable practice.

I’ve been checking that repo for many years. The guy is pretty chill, but several companies have taken advantage. They use the stack, post massive integration issues and demand free labor. Building a commercial product on top of a free open source software is pretty awful practice tbh
