If a metaverse is hosted by FB, it'll come with all the drama, nonsense and toxicity we see on there today. The product (ie, today's users of FB) is what stinks to high heavens.
It isn't the users, it's the platform and underlying philosophy of the business. They are factory-farming humans' attention; it's no wonder the result is dystopian.
I suppose the ultimate goal is compulsory participation, for more or less overt values of "compulsory."
