Frankly, the last bit is nonsense.  If nothing else, consider the situation
when somebody from UMN (which is a lot bigger than the group in question,
but hell with it - somebody really from that group) posts an analysis of
a real bug, along with a correct fix.  With valid proof of correctness.
What should we do?  Leave the bug in place?  Unattractive, to put it
mildly.  Write a fix and try to make it different from theirs?  Not always
feasible.  Write a fix without looking at theirs and commit it?  And if it
happens to coincide with theirs, then what?

FWIW, I do believe their claims that they tried to avoid introducing bugs
and creating problems in general.  So did RT[F]M, for that matter.
However, the very nature of their "experiment"[1] required deflecting
review.  With obvious effects...

[1] I won't go into its value, relevance of threat model, etc. at the
moment - proper comments on that paper will take more time than I'm likely
to have during the next couple of weeks.
