At this point I'm not sure how they could 'lose eyeballs' to those 3. There doesn't seem to be any kind of market overlap. Unless we're talking about the very abstract sense of doing _anything_ other than use a meta product is a potential lost eyeball in which case you might as well add the national park system to the list of people they can't lose to, and I don't think that's a useful way to talk about the cost/benefit of Meta's ai spending spree.

It is hard to imagine the level of spending they are doing if that is the sum total of their use case: shoring up a moat for which there really aren't any significant competitors in the first place. It seems like it can only be justified by eventually rolling out some kind of subscription service for... something, but for the life of me I can't think of what they might be able to actually sell to people or corps.
