I still feel like you're not getting NO ONE ASKED YOU TO... No one was rude or dissed you about it. You were told quite politely that it's not cool to use someone's work without permission. If you got offended by that then that's on you cause again, no one asked you to. If you use your own time to do something, cool. But dont say its disrespectful or a "diss" when you dont get the reaction you think you deserve.
Again, dont act like you're nice by being "forgiving" when you were in the wrong. It's a bit stuck up tbh.
It's cool you're gonna ask in the future but it doesnt really sound like you get why or agree. Yeah you may have thought it was nice, and I understand that, but rosie didnt want someone to use her work without asking, so dont act publicly forgiving and as if you have the moral high grough when you really dont.
(I'm not trying to sound rude, I just dunno how else to word it)
