The thing is the people that are upset and claiming this is the end of reddit are actually the ones that are disconnected from what most users want as evidenced by the fact that almost no one but a small vocal minority in a few places on reddit care anymore and when they try to get support in more popular/general focus subreddits they are almost unanimously being downvoted or disagreed with.
I think you vastly misunderstand the size of reddit's userbase. Furthermore, it's been my experience that a small vocal minority produce significantly more content than the average user. And the single largest group of people with enough time to post all the time are children.
Most users don't care about most subreddits. That's the way any big forum with many sub-forums work.
It's true that you get downvoted on Reddit for posting anything even mildly politically incorrect which is another problem with it - it's not a place to have any sensible political/worldview discussion anymore.
