As long as it was a legal option, I would immediately exclude all of Texas from having user accounts or advertising on my network. In the case of FB, public pressure would immediately work in my favor.
There are plenty of financial groups and apps that exclude based on territory due to local laws and regulations, I believe it is a legal option. It's a little flex and would result in short term advertising revenue loss but should end any further meddling in my "free" to join business.
"Your representatives believe they have the right to meddle in the content policies of our organization, they do not, until these foolish new regulations are repealed, Texas is no longer part of Facebook, please contact your representatives about this matter, a download of your account content will remain available "here" - Thank You, The Lizard King"
