Update: I didn't realize that this is essentially fake news. Apparently the governor inserted an amendment to neutralize the entire effect of the bill. She functionally vetoed it, but passed a non-functioning bill in name only to try to discourage further activism.
The key change to the bill was to create an exemption if a company claims it's for safety, but that's the basis for which companies have always justified their refusal to supply parts and diagrams, so it essentially means the bill no longer does anything.
We should still push hard for a right to repair in California. Is anyone currently involved with such an effort?
