How do people feel about open source projects asking for payment for features? I agree that it's presumptuous for people to expect features to be implemented for free just because they want it. It's pretty scary how toxic some open source communities are in that regard, though, with people going as far as flaming because their feature is not implemented yet. These days I also ask for money to implement specific features in my projects. Of course, the spirit of open source is still to do it yourself and submit a patch/pull request scratch your own itch) but not everyone can do that.
