RANT: Tell the truth or keep your mouth shut

My wife likes to play bridge; so do all of my other female relatives (well, OK; most of them, anyway). She plays once a week against my mom, sister, and aunt, using Yahoo! Games‘ Java bridge applet. Their applet usually works fairly well, but that was before I installed ISA Server, which is much more capable than the appliance firewall I was using before.
To make a long story short, you must open some ports to make the Yahoo! Java games work right. They admit this, but they get the port numbers wrong! Ack! I eventually found the correct answer at Tom Shinder’s ISA Server site, but I shouldn’t have had to– not to mention the 20 minutes or so I wasted trying various combinations of ports according to Yahoo!’s specs. Idiots.
So, word to all vendors: if you’re going to publish security information, get it right. Otherwise, I will have to sic Russ Cooper on you.
