If the managers you advise are working towards evil (say, they're having you find zero-days to deploy against human rights advocates in the service of murderous autocrats), by all means, stop working for them! But that's very different from the managers not being able to process your feature request until Q2 and asking you to fill out a Google Doc. This is not evil, nor will it benefit humanity to send in some patches to the other team's code and get it shipped tomorrow. Don't go looking for virtue there, either.
To reiterate my point - I'm not saying it's good that the things I'm claiming are true. But I'm saying they are true, and you'd better start by acknowledging the world as it actually is if you want to effectively improve the world as opposed to just ineffectively keeping your conscience clear. Expecting to find virtue at a for-profit business that isn't deliberately opting out of the system (and a startup that decided to be acquired is deliberately opting in) is misjudging reality. But in the same way, so is expecting to create virtue by making your employer a little more efficient at migrating VMs.
