The point of the post is that there is no way to opt out. We all understand more datapoints the better. But I also need to not be fucked with when I'm trying to work.
However it was not established whether or not field trials (A-B testing) was even the problem merely that they existed on the chromium processes. Even the stable version of the browser will likely have these options on the command line.
But that's true of shipping any bug and isn't guaranteed to happen with a field trial any more than any new feature.
(and the OP doesn't seem to establish that it has anything to do with the field trial, just that the processes were run with that option? Admittedly I don't know how they actually work :)
The difference is though, that I can choose the time I update Chromium myself.
