Speaking personally. I had the same reaction. I realized I could sign in using my GitHub account for MCC, which was… weird. Since it was just their normal web/auth page you could click around and do it in that tiny little webview. -_- Ridiculous, but I wasn’t going to make a new account to play a single player game. I did nearly refund it out of spite, but didn’t.
Yeah, I make a comfortable living doing software, and having kids didn’t work out. So I give out a few hundred bucks a year spread across the likes of Gnome, KDE, Mozilla, and some one off donations to smaller projects that end up saving me some time. Free software costs me more than proprietary software. Haha. (Well, unless I factor in the software I use for work… Then not even close O_o)
I get the impression that maybe the money sent to Mozilla might be a waste though. :-\
