I'm not sure I totally agree with that assessment. If we compare the sheer amount of resources and talent behind Meta vs. behind the Fediverse, it's clear that there's no way the Fediverse can ever compete in terms on innovation and features. Not to say that there aren't talented devs on the Fediverse - they're all pretty talented if you ask me - but Meta can just hire hundreds of similarly talented devs without even feeling the cost.
Really, the only way to prevent getting washed away by Meta (in development, in users, in culture, in basically just about everything) is to not associate with Meta at all. Co-existence doesn't mean we have to cooperate, after all. If the Fediverse shows that it has the userbase and staying power to withstand a full EEE "assualt" and remain standing, then I would be more inclined to take the "wait and see" approach. But I think as it stands now, Meta is very clearly trying to overwhelm the Fediverse before it has a chance to get going on its own merits
