I wouldn't paint with too broad of a brush in this instance, however. Yes, mudge is the ur-hacker, but also: he worked at BBN and DARPA (where he was extremely effective) and elsewhere. He probably has the most experience of any technical/hacker on the planet of working with executives in large organizations.

Agrawal's memo, in contrast, reeks of insecurity. The combination of how he's treated mudge and Rishi Sunak and the potential consequences of this complaint (particularly if FTC investigates and finds Twitter has not been following the consent decree) boxes him into a corner -- he won't be able to recruit the talent to solve these security problems and will be seen as an impediment to compliance/mitigation. I could easily see the FTC et al insisting on his resignation as part of a settlement. It's an own-goal.
