I have some loyalty in open source project I rely on and I regularly donate to them, particularly KDE and thunderbird.

Maybe loyalty is the wrong word - if they really go to left field, I would abandon them.

But I have a lot of faith in their design decisions and overall vision. Their software works, continues to work, and has always worked amazingly for me.

I also feel the same way about Firefox but donating to Firefox isn't like donating to thunderbird.
