Do you claim there are only unethical income choices? Or do you claim your expected standard of income comes only with unethical offers?

I think that you can find something morally wrong with most companies or practices within these companies.

Oh if you are looking for dirt, you can find dirt allmost anywhere, but im gemeral I do see a difference in making a website for a kindergarten, vs applying the most efficient tech to track and target children with manipulative ads.

Sure, but maybe you'll have to ad dark patterns, track users or create ad campaigns yourself for this kindergarten website.

Maybe that kindergarten want to cut food and people costs to make more money. Which could lead to very real consequences for the kids as well.

Yes and if you have ethics then you can say no. Also I never saw a Kindergarten website that even remotely did this.
