I think it would make more sense to make this opt-in. For instance, I set my profile not to be displayed a while back, but when I checked on this new thing, it was set to make at least some part of the profile public by default.
Keep in mind that Triplebyte profiles have no reason to exist except people looking for work, and that most people have a reason to want to be sure that a current employer does not have an easy way to find out that they're looking for work. I can have a HN account and it doesn't make anyone think I'm looking for work, but if an employer sees my profile on Triplebyte, it tells them at the very least that I was at some point looking for work. If they see it on Triplebyte after having previously not seen it, it tells them that something changed recently.
I would definitely think this should be an opt-in thing.
