Oblomov's overall assumption is that Meta will make a fedi platform only to "embrace, extend and extinguish". That is:
"when (not if, but when) it will defederate, it'll push a lot of people to move from the Fediverse to #P92 to remain in contact with the people there."
Almost like a platform made to fail just to gain more users.
One central quote to me, however, is this: "But interaction with users from other platforms does not raise awareness of the existence of these other platforms, as we see with Mastodon even now: a lot of people interact with users on other platforms and remain blissfully unaware, because Mastodon hides this information, both by hiding the platform of origin and by crippling content that isn't just short notes with no formatting."
I think this really hits the nail: The principle of the fediverse's philosophy is not just federation/interoperability. It also needs to design for #fediawareness / #fedivisibility , and it should always require freedom of #migration between platforms.
