They force researchers to do teaching between writing another paper, reviewing other people papers or applying for the next grant. At the same time, professors have too little exposure to actual engineering. After few years they only have the outdated fundamental knowledge and a bit of specialization in super narrow and ofter useless discipline. Teaching requires a different set of skills than research. Engineering is a more practical discipline than research. But because Universities treat all disciplines the same way, it all sucks. The US can attract people that are good in all three aspects but the rest of the world have professors that should be really doing one thing.
