That sounds like a very naive view on part of that developer. He probably never heard of Microsoft’s „Embrace, extend, and extinguish“ approach. This is going to be similar with Facebook. They have a lot more resources than all current instances combined and can provide a much better user experience. They are going to be the main instance on the federated network slowly starting to extend it and support features others lack. Making it a unique selling point until it’s too late.

And that’s not even looking at the moral/ethical standpoint of getting involved with Meta.

"then it doesn't deserve to exist"

When I hear that, I hear an implicit value judgement with Meta as the standard. The value of an instance is in if it can survive against a social aggregation to Meta's instance. Only then is it worthy of existing, if it can compete with the degree of funding, advertising, and account creation streamlining that we would expect from a social media platform giant.

When I hear that, I hear that small, self-hosted instances don't deserve to exist.

The counter argument is that standardized open protocols are important. So if a big corporation moves to adopt a standardized open protocol, it's a good thing for everyone, even if said corporation is sketchy, evil, or whatever.

It's kind of like Microsoft's adoption of XML for Office save files. Yes, they had ulterior motives, and the result isn't completely satisfactory for third parties who want to parse the save data. But it's still miles better than the previous situation where things were completely closed off.
