Certified? What's this "certified"?
People should have the right to repair, and have access to the necessary knowledge. Period.
Otherwise, we deepen the already vast split between the people who create and understand our technology, and the people who are merely consumers. Eloi.
We reached some kind of zenith around the middle of the last century - most the the kids who didn't live in the center city knew how to fix their bikes, lawnmowers, tractors, and cars. Some could fix their radios or wire a house. No more. Leave it to the "certified" professionals. After all, you wouldn't want a car on the road which was improperly repaired, it might hurt someone. Slippery slope, guys.
