Is anyone ever pissed that one exploit getting caught reveals other hacker’s efforts?

Like how that amateurish but high profile Wannacry attack revealed a much more lucrative Monero mining botnet that was running with the same exploit for weeks longer, but some script kiddie ruined it

I recall at least one "worm" that would patch the hole it came in by, perhaps so that it wouldn't have competition.

It wasn't one of those "healing viruses" either; it was exploiting a weakness and preventing others from doing the same.

This is also a solution (albeit with a race condition) to one bug that the Morris worm had: the same worm infecting a host multiple times and the multiple instances drawing more attention / stepping on its own feet. Other worms likely have had similar flaws.

(Any suggestions to eloquently un-mix the worm/feet metaphors?)
