they support good things to justify their bad things, and then the trap is laid.
they win if you let their whitewashing redeem and excuse them.
they win if you let your correct antipathy towards them bleed over into an indefensible antipathy to the good causes, even when the good causes they like dominate and deform the space for activism because of their self-interestedly generous support.
you must walk a tightrope, and of course the voices they finance will say you've failed no matter what.
