If you run a business on open source, you have to expect that some actors will contribute less than you would like. It is the price to pay for the advantages open source provides (contributions, widespread adoption etc).

The matter is that this "freeloading" is subjective as the GPL license does not really place any contribution requirements. Matt says it is about trademarks but the court stated TMs were not violated either. Dura lex sed lex, he will have to deal with it.
