In a nutshell, he says camera manufacturers apply the crop factor to lenses to get the 35mm/full frame equivalent, but then mislead the customers by not applying the crop factor to the F-number.
To illustrate, one example he gives is a Panasonic 12-35mm f/2.8 lens for a Micro 4/3s camera which has a 2X crop factor. Advertisers then say it's a 24-70mm f/2.8 full frame equivalent lens, when in physical fact it is a 24-70 f/5.6 full frame equivalent lens.
Then I thought back to how many supposedly "Tech Head" type reviewers I'd been reading, who went along with that type deception in their reviews of super zooms.
It also occurred to me that my actual camera has been misleading me. When I put a full frame lens on an APS DSLR, and set the lens to say F/4 and take a picture, the data in the photo says F/4 - what the lens was set to - when in fact the actual value was f/6 due to the crop factor.

There are too many posts for me to read here but there is a lot more to crop sensors/lenses/cameras than you can even begin to imagine.
As a paid professional photographer shooting for glossy magazines I sometimes use both crop and full frame but I never ever use compact/hybrid/superzoom/bridge cameras.
Just take crop v full frame, first there is not one that is better than the other it is horses for courses, FF has many benefits over crop, crop has a few benefits.
FF has better more easier controllable DOF over crop
FF Has a much wider range of "Pro" lenses available
FF has a greater Pro system available
FF lenses work on Crop sensors crop sensor lenses will NOT work on FF, one of the biggest mistakes people make, they buy a crop camera, later want to shoot FF but have bought a load of crop frame lenses, BUY FF lenses for any camera as they fit both.
Cropped sensors on my Nikons do allow me to extend my 600mm lens considerably where my converter on my FF will not reach, however it will be at the loss of quality magazines want. I would rather shoot at 16-18Mp on my Pro Nikon bodies that 16-36Mp on a crop sensor, and in low light, shooting in doors FF all the way, and I have shot Canon and Nikon and Canon has the edge on low light and colour though my gears is all Nikon
Also as in astro photography a crop sensor will not match a FF for quality, low light etc
The problem today is everyone who buys a camera thinks they are David Bailey, there is no learning a camera now, from my first camera when I was 12 to, today when I get a piece of kit I learn what it does for a week at least shooting in all situations before ever using it for work, people today don't buy a camera they are "sold" it, shame
