I am the DM of a campaign and have enabled content sharing in that campaign. If I use the join link to add one of my characters to the campaign, then deactivate that character, it also toggles the content sharing off (maybe only if it's the last character assigned to me, I haven't checked). There are plenty of use cases for wanting to deactivate a character you own in a campaign, while leaving content sharing turned on, so I presume this is a bug.

I have experienced this too.
