• Xitter: App is installed but only for the @YearsProgress notification (which counts in percentage how far along we are in the year. Just a fun gimmick I could get from other apps but idc enough for to get active)
• Trakt: Replaced by locally hosted yamtrack (It's a forked version and way better than trakt)
• Discord (if that even counts): Only to message friends. I don't engage in public server discussions outside of rarely asking for troubleshooting help
• Instagram: Only because friends send memes. Not much else
• Pixiv: Very rarely
• WhatsApp: Mainly due to family and RL acquaintances
• Reddit: Only at work while waiting for a loading bar to finish. Also I can't always take/endure the high volume neutral-negative leaning posting of political threads of my lemmy-feed and I can't be bothered to login to my lemmy account. But I never engage in the reddit posts with voting and commenting.
• Youtube: Very much so. Just the normal vanilla youtube experience. (And yes, I use Premium because I use it so heavily. Also the creators I watch get compensated more per view and I can't be bothered to subscribe to every patreon)

Edit:
Honestly, the reddit api-exodus helped me get off entirely from both reddit and lemmy and to reduce my reliance on it during lunch break.
