It is implemented in countries with less users only. To not piss off the majority in US/Uk.

I've had a similar phenomena. I've hit the lock when directly opening a subreddit link, but when I added a search filter etc I could open it normally.

I'm in the UK and the comments are all collapsed after a couple in each thread with "view more comments".

The most ridiculous thing is that if you click the "read more" link, it doesn't even work properly, the behaviour is incredibly stupid.
