I don’t think you understand how this works. I’m not the biggest fan of Facebook but even I know they’re not a charity they’re not a governmental entity. They’re out there to make a profit and if they can’t make a profit on their ad revenue then they have to make a profit in another way via a subscription service. So they’re literally giving you the option to either continue using them with ads or continue using them as a subscription service. Your other option is to completely delete your Facebook. I don’t see the problem here. You aren’t entitled to a Facebook page, no matter how useful it is to your personal life.
