Yeah, it just happened to me as well.

And the worst part is that even if we give in to their demands and log in, we’d probably only get six more months of old.reddit at most. By being complacent now, we’re basically showing them that they can do whatever they want.

So after they shut down old.reddit, they might require login for new.reddit too, or maybe cripple the website so much that it’ll be impossible to use it without their app (like Facebook and Instagram).

I guess it’d be better to write a userscript that replaces their UI completely, and/or start getting used to not browsing Reddit.
