I forked tt-rss back in 2005 for my personal use after I tried to submit a few patches that didn't "align well" w/ the developer. I wouldn't go so far as to say "massive asshole", but he did seem to be a challenge to deal with. I decided it wasn't worth the effort to try to contribute back my changes.
If you do check out the forums for it you will very quickly see that the developer is a massive asshole.
I wouldn't trust any code that a person like that writes to run on my machine.
