I think this depends very much on the project itself. Repair cafes are not by definition one way, or another.

For example, even tho I am not super tech-savvy, I have participated in 2 different makerspaces, in 2 different places in europe and both of these project had a very similar approach. We met weekly or bi-weekly do stuff in the workshop, and every month or so we had a repair cafe event. Some people wanted just their stuff to be fixed. Those who wanted to know more about fixing them themselfs, they were invited to attend the makerspace meetings.
