I'm surprised nobody mentioned his rant, and the way he lambasted Canon for not having developed a new APS-C sensor since 2009...
The folks at Canon seem stuck in a pretty bad rut, going on half a decade with the same old sensors in basically, all of their APS-C cameras...18 megapixels and .5 micron sensor process and still the on-chip A/D converter. Instead of upgrading the lineup, and coming out with newer and better sensors, they are down to making basically zero changes, but slapping a brand-new model number on what is, basically, the same body, but with a mode dial that rotates endlessly, instead of stopping at one end of the settings range. Wow! Innovation, fer sure,fer sure.
I would agree--newbies almost assuredly would demand that the instructional videos they buy be fore the EXACT,specific item they own. I see absolutely nothing wrong with separate T4i and T5i videos...it'd be a hard sell trying to tell people that one video is also appropriate for another camera. Calling him a tool for that seems disingenuous. I'ver worked retail sales--amnd it is very hard to convince people that one model is JUST like another model with a different name and a price that is substantially different.
