Yes, there's a reason I specified "product openness". React isn't a product and never could have been, so while I'm grateful to them for releasing it open source it doesn't really represent the same kind of play as Threads or Llama.
No, because they’re not exposed to users as features that they interact with. From a user perspective, they don’t ever see if it was made using those tools. They see the AI front and center.
They see AI features front and center. They dont see the backend (which may or may not be running Llama). Same goes for React although, with React, the framework is what the end user directly interacts with. So, by that logic, React is more of a product than Llama.
