Reddit’s mobile web experience really embraces this–even as a logged in user there is a frequent “Use our app!” popup that has been made progressively more obnoxious.

Once upon a time there was a preference option to disable the popup, though it would periodically become unchecked on its own. Then the option to disable it disappeared. Then the popup started appearing not just on page load, but after a period of time while you’re partway down the page reading, instantly jumping your scroll position to the top and making you lose your place. The ultimate effect has been that I swore to never, ever install their stupid app, and I spend way less time there on my phone, which is probably a good thing anyway.

Recently on mobile it's stopped giving me the option to even view the page anonymously, at least for adult content.

It gives me:

  "This is mature content and may not be appropriate for certain viewers. To continue, use the app to confirm you're over 18 and browse anonymously."

If you open any post with a lot of comments and you want to load more comments you must create an account - no option to disable. They really want to smother all mobile but the app.
