The author clearly went out of the way to put code in to signal to people that if you use the software and you are a company earning revenue using it, to help support the project.

This is clearly breaking the social contract that comes along with that MIT license, guided by what the author says.

When you break the social contract, and by doing so you induce people to follow you to do the same, eventually (given sufficient breakage) you end up in a world on fire; filled with violence and destruction.

This happens because non-violent conflict resolution can't take place without society, which itself is based on the social contract. A contract that you broke by trying to work around the authors intent.

It is well known that with people, "What you do in the small things, you do in big things that matter when everything is on the line". This piece of old wisdom, shows a cognitive preferential bias.

Ipso facto, you are supporting that world on fire filled with violence coming into being by those actions.

Sure you don't see anything wrong now, but that is blindness, and you can hold that isolated view right now while society is still in a working state, but actions and choices matter, and society moves towards the aggregate, either towards stability or towards chaos.

There is a time that is not far off, where that kind of behavior is going to have severe consequences.

If you did this without any resistance or seeing this as wrong, you have to ask yourself how many other things you've done that you just didn't notice? Are your kids modeling this blindness in themselves? Mimicking you as a role model.

Blindness puts people at a significant disadvantage because they often can't see the dangers they often create indirectly for themselves.
