For me it was Spotify’s patent on manipulating people’s mood with music, noped right out of there after that. I’m in a position where I can afford to go back to buying songs, so I actually did that (better for the artist and I don’t have to worry about any recommendation algorithm accidentally making me depressed because depressed = “more engagement”).
I’m not sure if it was related but, coincidentally, I found my mental state in a far better place about a year later.
