But Google 'gives everything away' (with indirect monetisation), both the products that succeed and the products that fail. So in that sense this is just a list of failed products which are the byproduct of innovation at such a scale, rather than an indication of what has worked and what has not for Google in the past. Surely in this case, going up against a competitor that needs to charge, Google would be at a massive advantage (legality aside) by not having to charge?
