Manufacturers' warning not to change tubes

I want to discuss what I believe is a very important matter.

Some tube amplifier manufacturers (e.g., Italian ones) strongly discourage customers from changing tubes in their amplifiers implying that their products are best optimized for the stock tubes.
I believe that "tube rolling" is a great fun and the benefit of owning/using a tube amplifier.

When the manufacturer discourages its customers from "tube rolling", this demonstrates the weakness rather than an advantage of its products.

It especially goes for automaticlly biased amplifiers.

I will appreciate azny comments

Many companies sell replacement tubes at a very elevated price. They want to sell you these rather than you buying tubes elsewhere. I do see the warrenty issue if you put in some bad tubes that cause the failure of the amp they should not have to honor their warrenty.
