Hi Mauri,

That is not correct. There are many application that require
neutralizing a GG amp. It is easy, cheap, and very reliable when
done correctly.

That isn't always an option. Some very good tubes have high
feedthrough capacitance, like the 3CX1200A7 and D7. The 3-
1000Z, when operated above 30 MHz, also benefits from
neutralization.
It really is not a problem when done correctly.
