"Trend Micro may have upset a few of you in the free software arena, but for those of us in the real world..."
The "free software arena" and the real world are one and the same, didn't you know? Free software provides most of the infrastructure of the Internet, in fact. (Especially if you include permissively-licensed stuff that vendors are able to fork and close.) What did you think was out there? A big Microsoft Exchange server installation running all the e-mail on the planet? NetBEUI broadcasts to find www.google.com and the like?
There's nothing wrong with providing a business around software, but there is a lot wrong with people filing bogus claims on stuff they've thought of and then taxing everyone else who strays near their turf. But I suppose "growing up" to people like you is about pretending to be all businesslike (flaunt that "corporate" thing as if we're impressed), and letting the likes of Trend Micro dip into your wallet whether you're using their stuff or not.
