WHAT? That seems like a gross misuse of funds because they're definitely not spending hundreds of millions
fixing bugs. They must be spending it on useless changes like the 300th UI refresh no one asked for. Firefox still sucks in every way imaginable and it's not measurably getting better. That number is shockingly unbelievable. Their crapware is not worth that budget.
For comparison, look at what the OpenBSD team has accomplished (and continues to accomplish) with a small core team and they surely do not have hundreds of millions.
