Unfortunately, nobody's gonna switch just because one person left unless it's a big influencer (which I am not). It'd take multiple people collectively leaving, and that's not gonna happen without something big. Fortunately, Twitter's current owner is, well... he'll likely cause that "something big" all on his own. Like how Reddit's API thing caused Lemmy to grow in size overnight.

When it does happen, I've already got accounts setup on a couple different places from the last time I thought the Great Twitter Exodus was finally happening.
