It is pretty offensive that they say "reddit works better on the app" when the only reason for that is that they broke everything on mobile (on purpose?) in a series of badly-implemented redesigns. I'm never going to install it, and I have all but stopped reading it because these prompts are so obnoxious. That's probably +$ for Reddit though. I don't understand why companies constantly do stuff that serves only _them…
For a site like reddit there is literally nothing they can't do with pure HTML/CSS/JavaScript.
Also, I like Firefox on mobile because you can block ads and install other extensions.
