If it becomes too antagonistic, people will change. The desire to build things is larger than any given iron fist du jour. Just ask Oracle or IBM.
Could you say the same about the Chrome browser? Google is using it to EEE the web (Embrace, Extend and Extend it till it's a monstrosity that nobody else can manage). That's pretty antagonistic. But did people change?
Sample size: 1 but I use Arc browser. It's still webkit under the hood (and in maintenance mode now), though it's actually pretty good and last I checked had most of the baked in google stuff toggled-off by default
