I think Mozilla’s breaking of the Firefox extensions ecosystem is probably the single most clueless and destructive (for the company itself) corporate action I’ve seen in the last decade.

It’s kind of like when you’re young and your parents say, “If you do that damn fool thing, you will hurt yourself.”

And then you do that damn fool thing, and you in fact hurt yourself.

Utterly predictable, and yet you do it anyway. That’s exactly what Mozilla has done.
