> I'm not crying about EA not getting its profit margins, but the cut Steam takes can really hurt indie devs.

Indies actually lose more of their margin than EA does, because Steam reduces their 30% cut to 25% after $10m in sales and 20% after $50m in sales. Few indies are doing those numbers, so it's functionally a discount for AAA publishers to discourage them from leaving for their own launchers again (EA did leave back when it was a flat 30% rate for everyone).
