99% of the affected channels make less than $100 per year. I don't think most of these types of videos are made with a plan to make money. I think people like making videos explaining things they understand.
Not everyone lives in the US. $100 for me or you may not be worth putting hundreds of hours into making a bunch of videos but it may be for others. My father's late friend used to do that since he was disabled and had few other options. He was in this sub-$100 category.
If you have a following in Patreon or any other similar platform, it shouldn't be that hard to jump ship and start uploading somehwere else. Any serious internet publisher should have at least one alternate channel for followers. I'd go with Twitter and a newsletter, so if YouTube decides to screw me, I can tell people "hey, I'm moving to [random platform here]". Patreon allows you to communicate with your followers too, so going, you can take your actual contributing followers with you wherever you want (theoretically).
