Fiduciary duty. It's a high bar, but "we abandoned 25% of our revenue in a fit of pique over our being required to follow the law on consent" probably gets you there.
That gets thrown around a lot but those folks are masters at corporate messaging. All you need to do is tie a bow and back the decision up with a long term strategy. I don't accept "fiduciary duty" being the pretext for any shitty behavior.
