First, I take issue with the idea of calling something "dumb" for trying to avoid modern app bloat, even as marketing. I understand the precedent of a "smart" device being something that backhauls your personal information to the surveillance industry (decidedly not smart!). But still, can we find a better name for the concept? "Native" ? "Lean" ? It shouldn't be about giving up some purported betterness of bloaty software, but rather about the benefits we get by doing so.

Second, it's kind of depressing that this is still tying itself to web technologies. What about a straightforward desktop client that uses a native desktop toolkit? I get that this is a difficult problem because a lot of protocols bake in reliance on web technologies and whatnot, but if I am looking for a simple graphical client I would expect something that aims to not simply dump content into webviews, nevermind still being dependent on an actual browser!
