How has Instagram largely avoided being associated with Facebook/Meta? - lemm.ee

I’d guess the simple answer may be that people don’t care/know, but for those that have ditched Facebook for whatever reason, yet still use Instagram, it’s a little surprising. Is it partly a result of it being a more focused/limited form of social media that filters out some of the stuff people didn’t like from Facebook?

I think people underestimate the scale of surveillance/tracking. People lump it in with “oh it’s just advertising”, similar to all the commercials you watch on tv. But it’s a completely different beast. Personally my eureka moment was when I set up a pi-hole and saw the staggering amount of creepy tracking on my devices.
Pi-hole? Pardon my ignorance but could you elaborate?
Pi-hole is software that runs typically but not necessarily on a raspberry pi. It maintains a list of known advertising and tracking servers and blocks them by rerouting at the DNS level. For example an embed in a page tells your computer to contact tracking.facebook.com pihole tells your computer that that website is at 0.0.0.0 instead of it’s real IP address. Nifty thing is that you can redirect all of your DNS queries at the router so even devices that can’t normally run ad blockers can take advantage of it.
