Well said. Boosted and upvoted... whatever those two things mean. Internet points to you, good sir!
I'll edit to add that the main thing you point out that I think most fediverse folks want to avoid is the investment that leads to the IPO bag of cash. When the incentive is profit, I think social media can only ever get worse for the average end user. Keeping these things small and non-corporate is great in theory, but who pays for the servers and other costs when/if it needs to scale?
