How is that even remotely comparable? I'm not saying anything about the quality of using MS tools - they're great - but they have a fee attached. They specifically say you will need to pay that fee within X years. Pretending the fee doesn't exist because you don't have to pay it until next year is what I'm scoffing at. Not the tools, the idea that MS will continue to make their expensive tools free when they have put an expiry date on that free license already.

Open source community supported tools are completely different. The price and license are very clear - $0 up front, pay for support if you need it. Don't want to pay for support? No problem. Need a new feature? No problem, pay someone regular rates to add it. You can't lose access to anything because you already have everything. You can't be sued into paying because the GPL specially disallows the creator from suing you.

We might be talking past each other here. No one is saying that it's a good business plan to assume that programs like BizSpark will never run out. That is of course a bad idea. But since no one suggested that, I assumed you were saying that using things like BizSpark at all is a bad idea.... which is not the case.

A valid business plan can be created that involves the pricing structures that Microsoft gives. You can have a plan that involves using a program from MS that gives you their software for free now, with the idea that you will eventually be able to afford to pay for them. Any company worth existing should be able to afford it eventually.

And, hey, look, it even happens that those windows of time can be extended. No one is saying that it would be a good business plan to rely on programs like BizSpark never ending... but it's still worth mentioning that MS has been forgiving if things don't go exactly as planned, and provides a way to delay the fees kicking in.
