Every negative poster was a rabid Firefox partisan 10 years ago. Now they barely hold on because they don't want a blob on their system and they want uBlock to work. Sadly, I have no confidence that Firefox won't declare next year that shipping a blob is necessary to the health of the web, and that some API uBlock relies on could be confusing to users and will be removed.
tl;dr it's a coordinated campaign alright, but it's coordinated by Mozilla's behavior, not by communication between the 90% of users that have left (30% to 3%) or the large percentage of those remaining users who are only staying because of their disgust for Google, closed source and ads.
Then and only then will I donate - to Firefox Inc.
The coordination is provided by Mozilla, not by us, the people who helped promote Firefox (and Netscape before it) and who feel that if Firefox ends up by the wayside while Mozilla continues to exist that it was all for nothing.
Firefox has been slowly but surely getting behind Chrome in many ways while all kinds of distractions have eaten up time, money and human resources that could have been spent on keeping FF alive and relevant. The long term path is clear, and something needs to change to avoid that.
