It says he lied, explicitly, just with slightly nicer words. Whether he did or not, that is the definitive reason the board is giving.

[1] ChatGPT "lying is defined as intentionally making a false statement. If you are omitting details but not actually stating anything false, this may not strictly meet the definition of a lie."

No it doesn't. "Not being candid" does not explicitly mean lying. It's like the old tea towel joke where the people at the bottom say "it's shit" and the manager one rung up says "it's manure" and the next one says "it's fertilizer" and by the time it's reached the CEO they're saying "it promotes growth".

Pretty much nothing changed positively or significantly after Snowden revelations, Panama papers etc etc

I doubt anything can damage the almost religious belief in chatgpt today. The inertia is huge.
