Queer baiting is a term that seems to be associated with celebrities latching on to parts of gay culture or hinting they're L, G or B for fashion reasons.
In some cases the critique is a sort of 'cultural appropriation' idea, but in the case of Harry Styles, I've seen a number of Fay men rather disgruntled at a handsome, flamboyant man being quite comfortable in not announcing to everyone what his orientation is, and they seem to think he owes them an announcement so they can claim and define him as fellow gay man or ally.
Frankly, I think a renaissance in 'Mind your own fucking business' is well overdue.
