So I just read Bill Gates’ 1976 Open Letter To Hobbyists, in which he whines about not making more money from his software. You know, instead of being proud of making software that people wanted to use. And then the bastard went on and made proprietary licences for software the industry standard, holding back innovation and freedom for decades. What a douche canoe.
To be clear - while I do consider it likely that it was as the other reply to your comment suggests - I won’t judge a stranger for cheating on their spouse as long as it is consensual and they don’t expose anyone (e.g. their spouse) to a risk of STDs
If it’s explicitly consensual then it’s not cheating because you are not breaking any understood rules of the relationship.
