I've always found it amusing that you cannot remove Facebook entirely from your phone without root access. Like whats even the story behind that?! Who thought that was a good idea?!
Now days we are putting crypto wallets on our phones, last thing on Earth on want spying on me is Facebook.
I also have some friends that are marketing through Facebook, I think it only works in local communities best. Facebook is a really poor place to conduct business in my opinion, and the thought of paying money and hoping and praying the advertising works is not for me. I pay for results, not hopeful results.
