I did not read the article as people actively calling the maintainers names. But just showing dissatisfaction that their day-to-day work was disrupted without warning by a browser feature changing.

And arguing about actively offensive people, i agree is moot and not the point of my comment. But those will exist regardless if your project is big enough, unfortunatelly.

My comment is about people disliking (in a sociably manner) the work made by open source corporation like mozilla, and that demotivating the paid coders. That is totaly on mozilla.
