Only one job ? Worked with a ton of ex NSA and CIA people in a large cybersec company.

Cybersec is not intelligence. The people suiciding in the article seem to be from intelligence rather than cyber. The fields are often conflated but they are different communities. One feeds data to the other.

Clearances are under more scrutiny for intelligence operators than cyber because, generally, the cyber people should not have access to finalized intelligence, the assessments and recommendations passed to decision makers. Cyber people also only work in cyber and know nothing about other sensor areas (ie human spy programs).
