Except in this analogy, Meta hasn't stolen food before. They run the largest bbq around, and have bought out previous corporate competitor bbqs, and now they're hosting a giant bbq one way or another, they're just suggesting you put a gate in the fence so that people can flow back and forth between the small community bbq and their large corporate one.
Is that going to make you nervous since they have such a cool giant bbq that people are inevitably going to want to go there? Yeah, but again, that's the case regardless of whether or not the gate goes in.
