I’ve moved away from most services offered by Meta ages ago (as well as Google to a large extent), but I can’t ditch IG overnight (getting there tho).

Edit: I don't use IG to browse (it’s cringe), just to upload my drawings (always a bit later than on open web).

Some of the people who follow me don’t know how to use rss or ActivityPub. Moving people away from these services takes time. Most of my friends are patient enough to, say, have installed signal instead of WhatsApp because I refuse to use it, but again - it’s hard to do this overnight.
