TMM has a long history of this. In fact, the major security breach that happened a year and a half ago had been going on for over a year. TMM knew about it and did nothing (they claimed they thought it was limited to a very few installs) and yet when OC3 Networks discovered a bunch of their customers who used NATS had the problem and attempted to warn people about it, TMM threatened to sue them and got them to shut up. It was only because a few courageous people described what was happening, and a bunch of people discovered that they also had the problem, that TMM was forced to admit the truth.

I know of another very large straight program that used NATS very briefly and found a ton of problems with it, but it too was threatened into silence.
