The alternative is paying a competitive rate, or splitting equity in a fair way, or both. If an "idea guy" doesn't want to get his hands dirty and doesn't want to pay someone to do the actual work, well...screw that guy. Nobody owes him anything.

It doesn't matter if it is easy or hard...if the idea guy won't do it himself, and he doesn't want to pay someone else to do it, it's not going to get done. And that's as it should be. If idea guy starts learning to code, he might learn enough to know what the work is worth, and will be better equipped to make the deals needed to get the hard parts done by competent developers. He may also gain the respect of actual developers; I wouldn't team up with guys who can't code at least a little.

I thought it was a very polite way to approach the topic. I'd be much more tempted to just say, "The only time I work for free is when it is work I want to do, on my own ideas, and where I own the result. Stop emailing me." But, I'm not renowned for my social graces.
