For your computer, might I recommend the "Old Reddit Redirect" extension, which currently solves the "for your security" ban on the classic layout for non-logged-in users?
More and more I'm thinking of what a nonsense world we live in. Once upon a time we hated Microsoft for trying to make us use IE. Now every company from McDonalds to onetime-open-Internet-darling Reddit is trying to force us to use their shitty apps, which amount to just single-site web browsers, which almost always entails granting way more powerful permissions, and which always renders you unable to block ads.
Internet of Shit.
I do have an old phone dedicated to the apps you simply can't avoid, but it spends most of its time sitting on a desk in airplane mode or powered off.
