@thunderbird Don't.

K-9 is good because it's independent. Mozilla's track record is too awful to not ruin it.

So just don't.

@thunderbird "Thunderbird is now part of MZLA Technologies Corporation, a wholly owned subsidiary of Mozilla Foundation"

If you say so, that's not what the legal documents say. You still also do the same crap Mozilla do to Firefox: opt-out analytic, tracking page opened by default...
