No offence intended but this is a first world problem.

Things aren’t black and white, sometimes there are practical necessities, Not saying the end justifies the means always but that is something to consider, There is some research showing the people with neurotic personalities have less job satisfaction (along with a variety of other negative outcomes). Doing stuff like learning some psychology and mindfulness training can help with that.

With that said there is such a thing called effective altruism , You can just give a bit part of your income, iirc it costs 15$ to feed a hungry child for a month. If you make 500K and give half of it to feed starving children but people get a few ads pushed to them is that so bad?

You could also try to work on open source, companies like suse/gitlab/nextcloud, or take the time to find a company that works on something more impactful , medical devices? green energy ? maybe a company like solar edge.

Getting proficient with git and it’s usefulness. It is one of the single tools that can make you incredibly more productive.

Could you elaborate?
