most people follow advertisements right back into the clutches of corpo-controlled products.

The thing is I expect places like Lemmy and even Mastodon to eventually fall to this behavior. The reason I'm even viewing them as services that should be must for the common user is the mere ability to even move out without having to leave everything behind (if you catch what i'm saying) thats the real core difference and hope that I have. The problem is again like anlumo said, defederation is definitely going to be a major hurdle and one where major companies will especially take advantage of.
