Permissive licenses permit a broader range of use compared to “copyleft” licenses.
“copyleft” here just being a cute way of being the opposite of copyright - instead of disallowing others from what they can do with “copyrighted” code, “copyleft” requires that they (upon request) share modifications to your code.
Permissive takes away this requirement to share your modifications. “copyleft” is considered more free and open source (FOSS), permissive is more business friendly.
I fell victim to this one on authentic “retro” N64 hardware, which has a hard plastic analog stick. Got an enormous blister right on the palm of my hand trying to win this tug of war. Of course, my young brain was able to hyperfocus on the game and completely tuned out any sense of pain in my hand. It was quite gruesome when I finally beat it and realized my hand was torn to shreds. I was at my neighbors place and I remember how shocked their mom was. She applied some cream that I think was meant for severe burns.
Nintendo would later run a campaign where they’d send you fingerless gloves for free to try to do some damage control on all the negative press when reports started popping up.
