It's still billions of saving that are not being used in taxes/licensing and being used for doing actual things for the public which is the job of the government and yes, that includes health, employment, education among other things.
> Microsoft brought computers in every home and made computers "interesting".
No, the internet did. I have yet to find "regular" people who were actively using computers at home before the internet era. Give a computer with no internet connection to a non geek, in most case he'll tell you it's useless.
> Gates has proof that he has helped the poor with billions of dollars. Stallman has possibilities and no direct proof of anything.
The cost of a Gnu/Linux distribution is estimated to the billion dollar, not to forget other big free software projects such as Samba and others. And it's all for free. Plus the saving done by governments are very real, they are real proof. This is huge for both governments, people trying to build a business and people living in 3rd world like myself (Peru) where people cannot afford to pay billions in licensing. I'm glad our governments is not wasting their money on Microsoft licenses as they are switching to free software. This is real proof, real benefit no matter how much you want to deny it and it's way bigger than all of Gates billions put together because once spent they won't be there unlike Gnu/Linux and Free Software which will benefit the world for many many generations to come.
The Gates Foundation vaccination programs are expected to save 7.6 million children's lives over the next 10 years. You don't think 7.6 million children living who would have otherwise died isn't a benefit that will last for many generations?
