assuming my understanding is correct, the. I’m not sure what the big deal is. someone sets up a fb business page, fb cancels or restricts access to that page because they don’t like the user’s politics, and then the user says “eff it. I’ll just set up a more traditional site for my business.”
Clearly you're not a business owner. Or a person who thinks before they speak.
When a business establishes a web presence, everything gets linked to it. All the search engines, various community entities, their other advertising, that's where their customers are used to going to find specials or communicate with them. When that gets abruptly deleted, you can't just go, oh well, I'll set up a whole new web presence and I'm sure everything will automatically link to it and my customers will know that I haven't closed up shop because my page is now gone.
So yeah, that's the big deal and it was painful to have to spell that out to you.
