The marketing material of Margolis are sure a bit over-the-top rants, but I really like the guy and its designs. That are quite simple at the end, but as written above, it is in business, so there are costumers willing to pay for a ready made working system. I'm a big fan of black enamel, while despising cream-white paint and colored plastics.
And for those in the US, should be relieving that their local optical design creativity, legacy from AO, B&L etc, is still alive and kicking.
In this wild world, aggressive marketing is a necessity... remember that Leitz, in the 1970s (allegedly) went bankrupt because they were making too good and durable microscopes, instead of advertising. The company was restructured, and today we have Leica, a soulless corporation selling standard Chinese microscopes at double the price and always popping up un my google ads. Good business!
A spherical aberration adjustable compensator, that's not a bad thing after all. (But the same result can also be achieved by simply adjusting the tube length

or the sensor position in an infinity system)
I'm dreaming since a couple of years of an "adjustable compensating eyepiece" for chromatic aberration...
