I think it's less to do with shying away from a comment (people can edit here no problem), and more to do with agency over your own information. It is our responsibility to be diligent about the detail we divulge in our lives. The de-activate button allows us a way to place another roadblock in front of further/future attempts to doxx in the event we don't want to filter through our own Hubski career's worth of posts/comments.

It was a small miracle for me when I used it recently - if only for peace of mind. I would like to see it come back in some form.

Hubski doesn't feel like an anonymous web site. I would be shocked if half the names I'm familiar with here genuinely believed this was a wholly anonymous space after the time they've spent here. Speaking for myself, discussing my life and interests (w/n a reasonable amount of detail) here sometimes is a good avenue to learn more of how others approach their interests. The people behind the keyboard would naturally bleed information of themselves in time given level of comfort.

EDIT: I love edits. Mostly re-arranging thoughts and adding others.
