I don't see why, unless you think they're lying and they filmed their demos, or used some other preexisting model. I didn't ignore the JWST launch just because I haven't been granted to ability to use the telescope.
Back when Imagen was not public, they didn't properly validate whether you were a "trusted tester" on the backend, so I managed to generate a few images..
..and that's when I realized how much cherry picking we have in these "demos". These demos are about deceiving you into thinking the model is much better than it actually is.
This promotes not making the models available, because people then compare their extrapolation of demo images with the actual outputs. This can trick people into thinking Google is winning the game.
