But that's beside the point, jaquesm said he expected browser vendors to clearly state what information they collect, I think Mozilla does a pretty comprehensive job at that:
https://www.mozilla.org/en-US/privacy/firefox/
And equating all data collection with spyware does NOT help win the battle. We're all on the same side here, but blowing things out of proportions doesn't serve the goal. It makes people give up.
It's fair to disagree with some decisions, and you don't have to opt-in for telemetry, but calling it spyware is unfair. It fair for you to say that you don't think it's necessary for your browser to collect performance metrics, and it's fair for you to not opt-in.
Equating things you dislike or find unnecessary with spyware is very dangerous. It gives other people the idea that browser choice doesn't matter. That privacy is impossible.
Note: we see extremism and exaggeration like this many places (politics included), and we have to be the ones holding each other to be reasonable. Otherwise, the opposition will frame us all as fanatics :)
jaquesm is merely pointing out that "use Firefox" needs a disclaimer today, whereas in the past one could simply use Firefox out of the box.
