Or perhaps it's because people are spamming their bug tracker from sites like Hacker News, preventing the necessary technical discussion from taking place.
This isn't just traffic. This is interrupting someone else's conversation to complain after reading an editorialized headline.
Having dozens of people post "I'm moving to Firefox!!" doesn't contribute anything. It detracts from discussion.
For exactly those reasons the thread has now been locked.
Sounds like Google devs to me!
