I agree with you there! But often it's not about *how* public things are, it's more about *where* they're public. In other words, many users I've spoken to who are either not bridged or are straight-up anti-bridge have chosen that route because they don't (yet) trust the entities on the other side to have that much ownership over their data. There's also a cohort who don't want to have to depend on *us* to bridge them either.
It's a lot more complex!
