Zimbra, or Microsoft? If open source is ever to have meaningful financial impact in the market, entrepreneurs should build their companies as if they want to be the next Microsoft, not the next Zimbra. Microsoft didn't put IBM out of business. Google didn't put Microsoft out of business. A lot of people might be putting AT&T out of business or NOT? Follow your passion, if you can. And you need customers to sell to and products/services they are willing to pay for. Or the Google/media model of selling advertising. Or... Not every company is a Microsoft, nor do they need to be. I'd rather see a dozens of competing companies - but that is my consumer bias. Monopolies (or too few companies) always seems to lead to abuse/corruption. »
