Basically the corporate whigs do not care about I.T. they care about risk management and keeping their jobs is the number one priority.
In a startup environment that is different. It is risk by its nature.
Unethical about using only MS because they own stock? Ethical as you can get as they own the company and are the customer. My guess is it is probably one of those media companies MS invests in to make
Money does talk and shit walk in business, but game theory in economics and finance dictate the shareholder does not always come first as everyone's priority is to keep his job. Buying software with known liabilities because some geeks on a website called Slashdot is a sure way to get shitcanned with no references FAST from clueless phb managers. There was a lady too in all the CIOmag press releases who was a SCO shill too. The PHB and directors read these.
While we know it is crap sometimes it is better not to take risks if you have a family to feed and just waste company money instead.
