@Glatorius @atomicpoet I don't believe it is naive at all. The proof point of a functional ecosystem is that it will develop a diverse range of funding options for operators from: "gift to the community", through "Mastodon blue", through to Fb style "we sell all your data". Maybe some innovative stuff involving micropayments to post/read as well, and the web 3.0 folks have something useful to contribute here.

It is practically a certainty in my mind that some instance somewhere will disable aliasing to prevent migrations away when they perceive that is in their narrow short term commercial interests.

There are also, as others have said embrace/extend/extinguish vulnerabilities inherent in any any open protocol.

How other instance operators respond to these things will define how things go long term.
