First off, you say the rest of us. Do you support lemmy financially yourself? (Genuine question, not trying to call you our or anything)

But that same thing can be said about all open-source software. I don't fully get your point. The reason the whole sync thing feels wrong to me is just because all that expensive fancy stuff, whether server hosting or the framework and protocol itself, isn't the service you're paying for. All that is free for the end user. Paying for essentially just the UI seems odd. It'd be like having a desktop environment for Linux that's paid only.
