Envy
Resenting others' AI-enabled or unaided achievements and wanting to diminish their advantage.
Her drawing is admired. He has found a reason to cover just that drawing.
Resentment of another's advantage, with a desire to diminish or deny it.
Fair criticism of appropriation or unequal opportunity differs from resentment of another's good.

How it takes hold
Another's work attracts attention. A question about assistance becomes attractive chiefly because it could make that advantage disappear.
Envy resents another's good and wants it diminished. Assisted or unaided work can be its object; the focus is the advantage rather than fair evaluation.
A legitimate provenance question becomes a selective weapon against successful rivals. Appreciation and learning give way to disqualification.
Finding the distinction
Illustrative situation: a rival's drawing receives deserved attention.
Too envious: inspection is used to obscure achievement.
Fitting: authorship and merits are fairly assessed.
Overcorrection: all criticism of success is dismissed.
Fairness can challenge appropriation without resenting another's good. Cynicism presumes bad motives; envy can acknowledge genuine achievement and still wish it diminished.
Ambition, disappointment and criticism do not prove envy. Grounds and purpose matter.
Counterfeit of Integrity: A selective authorship objection seeks to erase a rival's merit rather than correct a misleading claim. Genuine Integrity protects accurate attribution regardless of who benefits.
A response that restores something
Separate a warranted objection from the wish that another had less. Correction need not require humiliation.
An achievement may offer something to learn without obliging praise of everything its maker does.
Generosity makes room for another's good without surrendering legitimate opportunities.
