Why doesn't Ford (and most other Car Manufacturers) use catch cans?

This is the website for a catch can supplier: http://www.uprproducts.com/

Thank you for your answer! They are also claiming that intake valve coking is reduced with DI. They are counting on combustion vapors, and oil vapors will condense in the cans. The problem I have, when the cans get hot, condensation of these vapors are going to be drastically reduced, and these vapors are going to enter the intake anyway. Any comments? Thanks again!!

Thank you for your technical information!
