Almost every complaint I see about working in tech is 90% applicable to any industry. The problem in every company is other people. Some are greedy, selfish, dishonest. Some mean well but market forces demand unsavory practices. You won't escape it by trading a keyboard for a hammer or a pastry bag or whatever.
You have to either have a specific target in mind. Like you actually love doing some other thing and want it to be your career. Or, as the article lays out, just keep doing tech someplace more fulfilling.
Having spent time in tech in both government and nonprofit space, I can tell you the organizations are not very different from corporate ones. Day-to-day frustrations are very similar. You have to just take heart in doing something constructive for the public good.
