>>1880031old anonymous can't really exist in the current internet. Back then raids could take down or interrupt the functioning of entire servers and websites Now all the traffic is monopolized, it takes enormous effort to make even a small dent, the offending material is removed almost instantly, and if there is success against all odds the media goes ballistic over it, flooding this place with even more edgy normalfags, as seen with Gamergate, the 2016 election, and Chanology. The exception would be the Independence Day War, but that only worked because Tumblr's userbase is so easily triggered they suffer mental breakdowns just by us existing.
Old Anonymous can come back, but the tech and social media bubbles need to pop first. The killing point is that the huge majority of people don't actually know how to use computers well, and significant amounts can barely use them at all. So if anything happens to the big tech companies that dumb everything down for the general public, the majority of the general public will be completely cut off from the internet. I don't think the monopolies the current tech companies have could be so easily recreated once they fall.
