I have first and second hand experience on both sides of font licensing. I have several friends who are graphic designers for very large companies, and Fontspring has a lot of experience licensing to large companies as well. My first hand experience is that large companies often forbid their designers to use fonts until the foundry has been completely vetted first. The way the license reads is only part of the equation. They often research how reasonable the foundry is in general. Once the foundry is approved, they will buy the entire library just to make it worth the cost of their legal team vetting them. But if there is anything fishy in the license, or if the foundry isn't fast to ease their concerns, they move on. Unless it is a font that they absolutely want to use, they usually don't bother negotiating.
I license my type because it is the right thing to do. But I will generally backtrack and change fonts if I realize that the foundry is trying to—excuse me—nickel and dime me to death.
