I'm barely on FB but opted out of Meta's using my content to train their generative AI.
You have until June 26 to do so.
This 11-step process by Deborah Copaken, is a godsend.
Because of course Meta makes the opt out process intentionally obtuse + hostile in the hopes you quit from attrition.
Including burying the lede, the links, and even adding non-mandatory steps in the process to confuse you into thinking you need them.
It quite reminded me of Douglas Adams.
