Their incentive is really to make the Chrome Web Store a tractable problem with minimal human effort. That's about 75% of the incentive. You can't actually make any guarantees at the CWS level regarding safety of audited code if the API allows audited code to execute non-audited code.

May I be blunt? I grew up in it, so yes. I am. I was there for the Windows virus wildfires. I was there for the malware distribution schemes. I was there for the first wave of enshittification. For the dotcom crash. For the spam wars. For the search engines that didn't work. For the JavaScript injection attacks. For the world where "nobody knew you were a dog" as long as you didn't talk like yourself. I couldn't trust most of my relatives to use a computer the way we had to use them in the late '90s / early aughts. That's not a problem now.
For all its flaws, the modern system is cleaner, simpler, faster, and better for end users and no longer requires them to be super-nerds (and meanwhile, open and malleable devices are still there for the super-nerds to play with and work with). This was the goal---to make computers something that benefit everyone, not just the technorati and the priest-class.
May the past become a foreign country, hard for the modern mind to comprehend. May it always be so.
