The usual counter argument in this type of discussions is that it's Google's fault, because they changed their sponsorship, and there's nothing the execs could do. And then the counter to that is why pay big salaries if there's nothing they can do about revenues. Back to square 0.
I wish Mozilla setup funds for each project like it was done for Thunderbird. Then the execs can be paid from sponsorships etc.. but I personally have stopped to give to Mozilla any money since that change happened.
