You are taking so much for granted in this comment. World built on FOSS? You should be thanking Stallman on bended knee for making that possible at all. The rent-seeking situation before FOSS was infinitely worse. Today, you can spin up a cluster of servers with state of the art load balancing, databases, checkpointed filesystems, and a standardized OS without paying a cent to anyone in software licensing fees. Do you even realize the magnitude of this achievement?

Sure, billionaires benefit - so do the rest of us. A rising tide lifts all boats. Don't blame FOSS for the evils of capitalist rent-seeking; the rent-seekers of old have been toppled.
