I mostly agree with this, the point was that dinosaurs being warm blooded as a general rule isn’t well established or to be more exact no one is trying to establish it.

Dinosaurs span 165 million years there is enough room on an evolutionary time scale for them to take any shape and form.

That said the climate for much of their reign was very different, you probably didn’t had warm blooded aquatic life when the oceans were at 35c and finding dinosaurs in polar regions isn’t a proof for them being warm blooded as those region were tropical rain forests for about 90M years.
