Avoiding child support is a personal issue that can have many reasons. For all we know the woman swore she was on birth control, yet Jobs could have found out later from a mutual female friend that the woman secretly stopped taking it because she really wanted a child with a high networth individual. I personally know someone that this exact thing happened to. Is it wrong to withhold child support in that case? Probably still yes. But that's not exactly the same as just withholding child support because you don't think the woman you had a child with knowingly stopped loving you and wanted to go separate ways. If you got basically defrauded and forced into having a child because someone wanted monetary gain, you might have different opinions.

And trying to stop skyrocketing salaries fueled by endless poaching is also bad, but trying to only pay your employees 3-10x the median local salary its not the same as trying to flat out not pay someone.
