It was a gamble Yahoo! was desperate to take, so they did, and it didn't pay off in the long run (especially since for a large number of users it simply meant a one-time nuisance of switching the search provider back to a real search engine).
But Mozilla made out like bandits on the deal due to their executives smartly calling the future of Yahoo!. Good on them.
(we should all try harder not just to submit the story of the day, but also past stories that illuminate current affairs or can be seen in a different light with today's information)
How desperate must Yahoo have been to agree to these terms? Did Mayer really not know they were going to sell? Because even if they thought Mozilla would like the new owner this contract still incentivizes them to walk and collect two cheques.
And that money has been priced into the buying price of Yahoo, as the article shows.
I'm strongly in favor of Mozilla taking that money and doing awesome things with it.
(And admittedly, I'm pleased to see Mozilla get a payday that'll help them keep the browser market competitive.)
