If they found bugs in TeX, they should have reported them to Knuth. If they didn't want to "bankrupt" him, there could have turned down Knuth's check or just not cashed it, like the vast majority of people who have received Knuth's checks for bug reports. I'm sure Knuth would have greatly appreciated receiving the bug reports (and in fact would still appreciate receiving them now, if in fact those bugs exist).
