Its been that way for a bit. It wasn't born that way in a Vaccuum. Back in 2006-2007 it was much like this community with Digg being the Giant alternative.

Such is the nature of progression.

But even the non-default subs have been toxic for a hot minute. Its a shame really but the nature of people. At the end of the day you cater to the lowest hanging fruit....

Reddit itself is just a facade that links to all corners of the internet and consolidates conversation.

I admired their "hands-off" attitude. Yes, it led to some dark places with conversation that I disagree with - but that's why I could curate which subreddits I visit. And whether we're blocking unwanted conversations from the front page, or blocking them from the entire site, the outcome is the similar. The main difference, and one that I feel is important, is that in one instance I am the arbiter of what content is appropriate for me, and in the other instance it's a third party deciding for me.

Unfortunately, this policy was not helping them make money, and, like you said, they have a right to kick someone out of their house if they're being destructive. I understand their decision. They've put a lot of work and time and money into that site, and I recognize that they don't owe me - or any of their users - anything.
