Dude I would relax for a moment before jumping to such conclusions. To be honest most splits work and work well if you put in the effort and work hard.
Furthermore peoples methods and opinions can and are allowed to change. For example I was on a strength training program for about a year and I switched to a more bodybuilding style of training for 4 months, gained 10lbs and increased my strength.
I could come to the conclusion thus that bodybuilding training is the best method to increase my strength but in reality its more likely that the difference in methods contributed to my gains.
What I'm trying to say here is that perhaps recently CT has been adapting his methods more to this style of training and seen some great gains.
You offer no question and just an accusation which I feel is very shortsighted. Perhaps try both 4x a week and 6x a week and see how you feel and then come to your own conclusion?
Like I've stated previously, some of the best splits are 4x a week and some of the biggest and strongest lifters follow this frequency.
I see nothing wrong with splitting up the volume into more training days personally and I will try it myself and see how I feel.
