Even though I dont want to and hate it, I have to cause pretty much everyone elae uses it, cause everyone they know use it etc etc

Facebook marketplace is more popular than Craigslist, offerup, etc. at this point. And there is an enormous knowledge base for various hobbies/activities via groups like gardening, mountaineering, etc. People use Facebook for the community. I hate Meta as much as anybody, but it is good for many things.
