While I want everyone to freely choose to end their Meta accounts, and while I agree that one should never be in a position where a unilateral decision can block access to one's personal data and contacts, we must not be smug about what's happened here.

Meta is like any monopoly platform: They actively and aggressively get as many people as possible to put as much of their life as possible onto the platform, and deliberately make it difficult to leave. Not to mention that they also effectively dominate so much of the “share with your friends and colleagues and customers” capacity, that any competitor would have an enormous disadvantage and therefore these people cannot leave Meta easily.

The solution here is not to shame people for still using the dominant platform, when that platform's switching costs make it immensely difficult to leave with one's data and connections intact. We must instead agitate for change so that there can never be any profit-motivated dominant platform. This will carve out the room for a rabble of competitors that are each small enough they cannot dominate, and must treat their users with respect in order to keep them.
