Every company that applies to YC can expect to want $500k+ of capital at some point. It's extremely rare for them not to. The "no, I'd like just one" reaction doesn't make sense for a company that's aiming for a $billion+ valuation, and those are the only companies that YC accepts.
This makes sense if you wanted to sell YC 7% or more of your company. Some of us want the benefit of YC without giving up so much of our company, and the new standard deal doesn't do anything for us.
