I don't get this:
There was an FSF blog post from either earlier this year or last year making
a list of software the FSF was using, and Thunderbird was in the list. It has
been absolutely common knowledge that Thunderbird was in Trisquel. People
talked about and recommended Thunderbird all the time.
Look at this, an issue about this from 2 years ago:
https://trisquel.info/en/issues/6456
And you're honestly saying that Thunderbird was in Trisquel "by mistake" for
all that time, and the mistake was only realized when RMS sent an email about
it?
What's the trigger here? I don't get it. Did RMS really need to personally
announce that this is a problem before it was taken seriously?
