The bad stuff is irrelevant, but by the same argument, so is the good stuff. This isn't really about Bitcoin as a whole; it's about a specific assumption in the community (everyone wants to be tipped, people who are worried about taxes are misinformed and/or holding up an unjust system) that manifested in a specific use case.
It wouldn't be really accurate to TL;DR a Linux kernel CVE as "somebody introduced a bug in prctl - big deal. Linux can be used for a lot of good stuff." (Nor "bad stuff".)
