This is a small detail that is easy to miss.
The "higher-end" MBPs with 4 ports are only availabe with the intel CPUs for now
The "we integrated thunderbolt" bit is also implying an untruth that nobody else does that. Intel did that last year with Ice Lake. AMD will do that next year when they upgrade their IO die.
The point is that it's mostly Apple's fault to begin with. They choose to use outdated processors without integrated thunderbolt. They chose to add their massive A10 die instead of a normal, optimized SSD controller (not to mention this screws over data recovery and SSD replacement). They are exaggerating at best about RAM as the chips merely sit beside the core. The only thing they should really claim is the IO die and even that's nothing too special.
