Linux Foundation Income Quick Numbers

The Linux Foundation is expected to continue to grow in year 2013.
New members that will start donating money to Linux Foundation include companies such as:
- FreeScale
- Amarula Solutions
- SIM Technology Group
- Superb Internet Corporation
- Symphony Teleca Corporation

 
It must be highlighted that, to become member, a company must pay at least between 5,000$ and 20,000$ a year, for a Silver membership.
Moreover this, Gold Membership costs 100,000$ a year, and Platinum Membership costs up to 500,000$ a year.
Taking into account that, by 2012, exist:
- 8 Platinum Members
- 16 Gold Members
- 139 Silver Members
With a quick calculations we have that, by 2012, Linux Foundation incomes, just with the Membership donations, were:
From:
8*500,000 + 16*100,000 + 139*5,000 = 6,295,000 $
To:
8*500,000 + 16*100,000 + 139*20,000 =8,380,000 $
However, Linux Foundation have also a big amount of individual members, that, together with previous number, surely make Linux Foundation incomes to be above 10,000,000 dollars.
So, it is obvious that, FLOSS is not a matter of altruism. Companies as well as individuals are predisposed to invest money on certain projects to continue growing.
