If I based my concerns off of what I worked on, I'd actually probably be cool with it. Things are generally taken very seriously and the general discourse around how things are handled (at least to my knowledge) are wildly exaggerated. However, knowing just how things work end to end and how Meta tends to handle things, I think accepting something like the terms they lay out will give them freedom to do whatever they want with whatever they want.

That might seem obvious to most folks but I guess it's more just be saying yeah they'll take as much as you can give them.
