The sticky bit I have is facebook marketplace - it's wiped out the other classified marketplaces in my area.
I'm not making any serious money off the old stuff I sell, but the alternative to selling it (or even giving away low-value stuff that's still functional) on facebook is basically just throwing it out / destructively recycling it.
I maintain Meta accounts for two purposes. Facebook Marketplace, and following local businesses on Instagram because it's become the de facto platform for many artists/bars/restaurants/popups to distribute information. I don't add friends, I don't "like" posts, and I don't doomscroll the garbage they put in my feed.
I'm willing to give Meta the information that I enjoy old cars, bar trivia, and breakfast sandwich pop-ups.
