>Giving up control is how it works. It's how it's always worked,
no, it hasn't. Open source software, like any open and cooperative culture, existed on a bedrock, what we used to call norms when we still had some in our societies and people acted not always but at least most of the time in good faith. Hacker culture (word's in the name of this website) which underpinned so much of it, had many unwritten rules that people respected even in companies when there were still enough people in charge who shared at least some of the values.
Now it isn't just an exception but the rule that people will use what you write in the most abhorrent, greedy and stupid ways and it does look like the only way out is some Neal Stephenson Anathem-esque digital version of a monastery.
