Well, I don't think Cheers posts things out of malice, even the bit in the other thread. He's of an older generation that most if not all of us, and for the most part, when someone points him in a positive direction for things like terminology, he usually follows.
And I think he's been out of the country too long to judge what the NHS is like on almost any level. If he ever returns home, he will see that the NHS not as horrible as some of the press makes it out to be.
