This post has a curious absence of even mentioning distrust of Google with yet more of our personal data, which was a major theme of discussion in all venues I saw this issue mentioned in, and certainly seemed to play a major part in distrust of an opt-out configuration.
This seems to be a nice example of maintainers of a popular open source project listening to feedback from the broader community:
> Thanks to everyone who took the time to write constructive, helpful feedback. Those discussions are open source at its best.
