Of course, and everyone agrees on that point.

The problem is when people try to rewrite good engineering 
or science or badmouth others based on some esoteric lucky 
design.

The fact is a 572B is a lousy tube at ten meters, let alone 
VHF. If it works in a particular recipe then that's fine. No 
problem. Nails work fine for cotter keys in some 
applications.

That doesn't change the fact it is a poor tube choice.
