On: No, I won't be your technical co-founder

It's infuriating on both sides, and I see where you're coming from with your comments here. I presume the OP wouldn't ever say "you're replaceable" to someone who actually has (and demonstrates) a network of any sort - it's the people who have no network whatsoever, but are seemingly unaware that that's important, and instead want to focus on 'an app!', that are the real red flags.

Likewise, yes, many developers are also replaceable, though few like to think they are.

I think that the problem is the idea that "a network" is the only value that a business guy provides to a company...

True, if that's the only value someone presumes the other party is bringing, that's a problem. OTOH, I think people undervalue the value of a tech/dev's network - including developers themselves.
