> Do you know who we should thank for all businesses killing their own online presence and migrating to Facebook? I'll give you 4 letters to guess: G.D.P.R

Pure, absolute, grade A bullshit. The trend predates the GDPR and is widespread among US small business and organizations that I guarantee you have never heard of that law. It's not a factor at all. They use Facebook because it's as close to zero set-up and maintenance as it gets, it's free, they already know how to use it, and "everyone" has it anyway.
