I doubt anyone could pay the man enough to blow 40 billion to tank a website. The moment you break something, the users will find a replacement and go there. This purchase was 100% ego.

The nice thing about Lemmy is, it doesn't care if you "go back to reddit". Nobody is monetizing you here so nobody is incentivized to try and get you to stay. Not having fun using Lemmy? Go on then. Reddit is probably where you are happiest. This is a newish system that has exploded. If you can't be inconvenienced by glitches and growing pains in a FREE service, by all means, go be a product for Reddit to sell.
