I don't know enough about the situation to say which bucket it falls in, where possible buckets include at least "there's nothing morally or legally wrong with that", "that's morally dubious but probably legally okay", "that's illegal but unlikely to be prosecuted", and "that's illegal and you got lucky". Compensation of employees of a not-for-profit is certainly allowed - that's a different thing than returning profit to shareholders except when it isn't (in which case, IIUC, it comes with restrictions, which isn't to say it's never abused, which isn't to say it's never/always prosecuted, etc, etc...). I explicitly admitted the possibility of wiggle room around the restrictions - my point was about what the restrictions referred to in the first place.
