I trust you are nowhere near membership of the Governance Committee.
Your position is not merely "morally dubious", as if it were solely a matter of differing ethical judgements. It would in certain circumstances invite ECF to enter unlawful transactions. I have in mind breaches of Anti-Money-Laundering legislation and similar regulations which require organisations to secure the provenance and legal integrity of monies they receive.
I'd have thought the Scheinberg sponsorship would merit at least some pause for thought, including a view from the Governance Committee
