AT&T was a monopoly; many consumers didn't realistically have a choice. When it comes to social media, FB isn't a monopoly. Twitter, SnapChat, and TikTok compete very successfully in the same market. You could include iMessage and YouTube in that segment too depending on your definition of social media. I could argue the same for Apple; other companies compete successfully in the manufacture of phones, personal computers, and tech accessories. A company can be large and powerful without being a monopoly.
