Reddit is (was) a social network with tens of thousands of communities and only ONE instance. That makes it easy for a small number of arrogant, greedy billionaires to ruin things for everyone.
Lemmy doesn't make that mistake. By being decentralized, it prevents exactly that sort of thing from happening.
I've already started moving over to lemmy but I'm also seeing some weird stuff on my Reddit account. I've had more 'Followers' sign on to my account in the last 2 weeks than I've seen in the last 3-4 years. I don't believe these are real followers. What would be the reason for this? Is Reddit playing some sort of statistics game with long-time Reddit accounts?
Well that's the nice thing about a decentralized platform. If someone tries to "take over" Lemmy, they would have to take over all 1,100 Instances on separate servers in different countries to ruin it.
