To play devil's advocate, without A/B testing a lot of decisions would be made with insufficient relevant data, and lead to subpar results that affect the many negatively form the road.
counter-point : the companies that are most famous for A/B testing routinely are also the ones with the most notoriously non-existent customer service departments globally, facebook/google/amazon/ebay. Groups that harbor dissatisfied customers by essentially being 'the only show in town.'.
so, what i'm saying is : I think a lot of companies align themselves with the cash first and then measure whether or not the negative image/user impact is manageable .
A lot of decisions made with A/B testing are also made with insufficient relevant data, but it's less obvious since it's easy to think the A/B results cover everything.

Sure. Let me just A/B test whether or not you'll respond positively or negatively to having your news delivered via push notification or delayed by 10 minutes.
I'm sure you would appreciate being tested on without your consent, just so that I can make an extra quick buck at your expense. Nothing amoral or unethical about it.
What do you think about slow rollouts for new features? Like, we think this new push notification system will be loved but let’s ship to only 1% of users in case there’s a horrible unforeseen consequence like occasional 10min delays? Dashboard goes upside down -> revert then work through logs to figure out what the hell went wrong.
