Reddit and its ilk are not the open web, they've been showing that clearly for years with the most recent bullshit (from any of them) just underlining what's already written on the wall.
Web 2.0 failed because of twits like Elon, bozos like Bezos, fuckers like Zuckerberg and Huffman who doesn't deserve a rhyme. We don't need them and never did, they're learning that right now.
