That's unfair. Engineers don't always get to exercise their skills or best practices if their CTO gets in the way. Or if other external obstacles block the CTO. I've worked with very talented people who are totally wasted because the company just doesn't care to get the tech right when it comes down to making that investment.

Autonomy to get things right when it's the right call is sort of a rarity and a real luxury in my experience. I've built a ton of things I knew could have been built better if the rest of the company saw the value in doing so.

When given the option to do your job as asked or quit because you don't have your way, I'd rather just do my job and wait for opportunities to improve things if they present themselves.
