RH had 343 millions $ of earning in Q3 of 2012. The company had around 5300 people on payroll at this time. According to SEC fillings, the expenses for Q3 is around 240 millions $.
Mozilla foundation, in 2010, spent 145 millions $ in expenses, for a payroll of around 250 people ( according to Quora and their own website ).
Canonical has around 500 people on payroll if i am not wrong. If I just divide by 10 to match the numbers of RH, that would mean operating expenses of at least 100 millions per year ( 4 * 24 millions ) for Canonical.
If I take the one of Mozilla, that mean around 300 millions of $ in expenses per year for Canonical.
So please now explain how 10 millions of $ put in 2005 on a bank account does address the sustainability in any way.
Either someone put something like 290 millions of $ to pay everybody for 3 years ( without any investment ), or there will be massive layoffs ( like 97% of the current work force ), along massive cost cutting changes ( like, not using one of the most expensive part of one one of the most expensive town of Europa as HQ, or not doing bi yearly events that cost around 500 000 euros to organize ).
