What an odd group. Wonder what the common thread is? How is it that these companies cmae together to sign this letter?
It looks like a list of companies that have a lot tied up in their trademarks. Monster Cable is always suing other people over the Monster name. Xerox has always been on the verge of having it's name genericized. Fashion houses have almost their entire value in their brands. At least the tech companies can fall back on their patents to defend their turf.
Just go with the flow control, roll with the crunches, and, when you get a prompt, type like hell.
