It's also stopped me uploading video to Instagram because now "your video will be uploaded as a Reel" and controlling the "share to Facebook" permissions for Reels isn't possible via facebook.com, you have to use the iOS app (which I do not have installed.) Instagram won because it was a low-friction way of sharing images (cf Flickr at the time which was ungodly frictional.) Now it's just friction-a-gogo and if the communities I wanted to connect with existed elsewhere, I'd go elsewhere.
