I've interacted with local businesses that use a Facebook page as a replacement for maintaining a website that they own. The rationale I've read is that their time is best spent providing their quality service versus learning website development (even with a block-based website builder), and hiring a web developer is too pricey, when they can create a Facebook page that is easy to set up.

Most importantly, it's easy for them to update and maintain a Facebook page, versus an independent website.
