I really like tridactyl, but I haven't tried any alternatives yet - following this post with interest :))
Same I just went with Tridactyl without a particular reason. Though their native messaging part, where you can execute stuff like your editor with a keybinding is a nice addon that others don't have.
So you went out of your way to find something on a GitHub page of the developer of the extension I use and took this screenshot, for what? To prove me this extension is worse than others? I'm not getting your point.
If you don't like it or political views of developers are important part of your process of choosing software, nobody is forcing you to use that extension. I suggested whatever I use because it fits my needs, no need to tell me if I'm right or wrong in using the software I choose.
I was citing my source. I don't have any idea what matters to you in your choice of software, but if this did matter, I wanted you to have the information to make the best choices for yourself.
