At the time, the idea behind that was that _maybe_ this would make the vendor pick it up and provide a cloud-free stock experience. In that case, it would've been fine-ish if they'd monetize the work as it would still be very much beneficial to everyone. That sentence in the docs is not directed at those. You can't reason with corporations.
Instead it's directed at that crafty kind of individual that would sell pre-rooted robots just because there's money to be made. Those people that purposefully refuse to share knowledge so that they can monetize it. I am aware that it won't stop them either, but at least there's an attempt I guess.
Given what I've learned in the process, I can't say for certain that I'd pick the Apache-2.0 license again but it is like that now. As far as I'm aware, re-licensing would require asking every single contributor for their consent. I'm not too fond of doing that tbh.
