Pretty disappointing to see something I've spent so much time with go down the tubes like this. I know that for a lot of people, Reddit has been dying for years, but I've stuck to old.reddit and my Android apps, and haven't looked at /r/all in a long, long time. I unsubscribed from all of the big/default subreddits, and just hang out in my happy subs where people (mostly) are people and aren't lunatics, and it's still been a nice place.
Killing the mobile apps is pretty much the last straw for me. I'm sure I'll still click on search results from Reddit sometimes, but I won't be logged in anymore and it will only be on a browser with ad-blocking and privacy features. There is no way I'm downloading their app.
If they were to go this route for all users, I would simply never use Reddit again on my phone. And yes, I'm in the minority, and yes, I know they don't care about losing me, but man, what a bummer.
