The nice thing about being a non-profit is that we can include a tracking blocker for that 44% right in the browser, without it being counter to our business interests.
Would you mind to expand your point of view and provide evidence? Are you perhaps referring to the cliqz experiment that was ran for less than 1% of german firefox downloads? Are you sure you are not blowing things out of proportion?
Germany has rather strict privacy laws, so it sounds like the worst pick for something like this.
They're also planning [] to send more detailed browsing history as telemetry, so there's that.
I'll be impressed the day this is turned on by default, or at least proposed as an option to the user after installation :).
You can already enable tracking protection globally in the options. It's on by default for private browsing, but it does break a few sites (like any adblocker).
