A lot of these folks are working on the assumption that Hawking Radiation would have evaporated all small primordial black holes (the kind that could traverse the earth with little to no damage).
However Hawking Radiation is a testable prediction of a theory that has yet to be tested. I dislike that physicists tend not to speak of Hawking Radiation in such terms since it is not a fact.
In particular, I would argue that the Black Hole Information paradox isn't a paradox, it's an evidence against Hawking Radiation which in turn pushes back on quantum mechanics. Most of dark matter may very well be explained by small primordial black holes we're not (yet) well equipped to detect.

It's pretty hard to observe a black hole and run tests on one after all. It took us to the space age to start getting a lot of practical observational proof of relativity for example. Now its all confirmed relativity for now but for a lot of these other things we are sorely lacking. Hawking radiation is a good example of that as you pointed out. How do you even get observational data on hawking radiation without the starship Enterprise anyways?
