It's quite inconsistent though which is really frustrating. I can look at the imgur homepage feed, but if I go into a specific post and accidentally click anywhere it throws a modal up that can't be dismissed.
If I go on a specific subreddit or post I can freely look, but reddit homepage now pops a modal you can't dismiss.
This is on mobile browsers, of course both sites are pushing their apps.
I am sure it doesn't align with their incentives so they don't care, I will never have an account and never install the app, but why block me from viewing the site if I am still seeing the ads? Does the free ad model just not pay anymore, or is the selling user data model just that much more lucrative that they would rather no user at all if they aren't logged in?
