You may be over analysing things for I don't see were the fighting came about.
It is merely talking shop. Once a manufacture takes it upon him or her self to offer the internal parts of their product for all to see, you will embark some that will comment on the components, or in this case the arrangement of the design.
It regards to Crest, it shares a lot of characteristics of the old Professional series in terms of how the components are arranged. Although no longer in production, Crest Professional Series is still classed as a highly respected design.
I don’t know any small manufacture would consider that degrading when there are lots of small companies mimicking amplifier arrangements from designs that are inferior to the Crest Professional Series.
