You will when if Google decides they're afraid of your product giving you some leverage and decides to give a clone away for free to undermine it's value and damage your business.
Exactly the strategy that Microsoft used to destroy Netscape.
It stifles innovation because they don't need to do the hard work to advance the state of the art. They just need to copy the work that's already been done and let the free price and privileged advertising position do the rest.
It's good for Google, but bad for the rest of us. You can say 'but don't users benefit from getting stuff for free?'. Well yes in a way, but we all lose because of the stagnation it causes.
Again, pretty similar to what Microsoft has done in the past. It may be very hard for corporations that have a quasi-monopoly to avoid falling into this pattern in general.
