The problem with media platforms like Reddit and Twitter is that they take place in a single Instance, with thousands of communities. So it’s easy for one person (like an Elon Musk) to completely screw it up for millions of people.

With Lemmy, everything is decentralized. Communities are spread out and duplicated over hundreds of Instances in many countries. So if somebody ruins one Instance or community, people can just hop over to the second or third most popular Instance, and the original instance will dry up and disappear.
