No, it isn’t, because of resilience. reddit as a gigantic instance would take out a lot, but the whole ecosystem of UI, clients etc. would have stayed identical. It would be a much softer switch. Shutdowns of large instances are an issue and lemmy’s user history is not portable (hopefully it will be). This has better future prospects.
I never thought YouTube’s business model was very sustainable. As the world economy goes down, so does the value of ads. Creators or consumers need to pay up for all the bandwidth and storage. The question is about what is a reasonable price. Are low tiers for $3/mo. possible along with premium 4k options or does everything need to be at more than that?
