This isn't about empty credentials but about track record.
His track record is that he has used the device, that he has written software for it, and that he helped investigate the issue. He says the device is slow, and he says what he considers slow in terms of seconds.
I don't think reporting a simple observation like that or paying attention to someone reporting it lays claim to any kind of usability expert status. He credibly said Q. I don't know what that has to do with X, Y or Z at all.
If someone tells me the traffic light is red, I don't reply by asking whether he's a traffic lights expert.
But if you're just expressing general astonishment about waves of popularity and public attention, I'm with you. It's futile to resist that though. I think the only way to deal with it is to judge each statement on its own merit.
