Putting focus on short term revenue can hurt long and medium term revenue, and thus degrade the value of the company. Of course if you're already hunting for the next gig in another company, then the short term bonuses may be the only things that matter.
I cannot find the source but I think it was Rushkoff who used a wonderful phrase: extracting wealth by destroying value.
It highlights the underlying problem better than anything I can come up with.
1/ its a source of revenue and get VP's bonuses for diversifying mozilla's revenues
2/ its a test to see how people like if mozilla starts incorporating 3rd party cloud services in the user-agent
(doesnt actually sound evil put like that does it?)
result:
1/ some few people get paid a few hundred thousand/year
2/ mozilla alienates people, loses market share
3/ said vps will leave when mozilla can't pay them bonuses no more
(I think that's sadly close to the truth)
