Shooting yourself in the foot, part 53326: Mozilla
Step 1: with bad design decisions one after another (Australis is a shining example of that) slide yourself into irrelevance;
Step 2: when market share goes below some threshold, the main sponsor diminishes (or suspend?) payments;
Step 3: in retaliation, hurt the users by forcing om them a sub-par alternative as a default;
Step 4: profit bleed even more angry users and go even faster into irrelevance.
Brilliant strategy Mozilla!
Myself, I am still using Firefox for the time being, but that's exclusively due to Gecko.
