Its already frustrating enough having to use Facebook just to look up a restaurant's information, the set times for a concert, or whatever about a local business or event. If all that stuff starts to disappear behind a meta-verse wall, I might just leap off the nearest bridge instead.
Given the efficacy of Facebook's targeted advertising this may be inevitable. Some random website containing a restaurant's information simply isn't worth maintaining if all your customers use Facebook anyway.
Not a good plan for any business, I would think. Would be nice to see more businesses on Mastodon or (gasp!) just run their own websites again. Can you imagine how difficult it must be for a business to buy a domain, hosting, and slap together a static site in this day and age?
