re: Anyone giving like $5 per month or $20 per month to an NIL cooperative?

Hell no.

A&M has plenty of money. My personal donation money can do so much more good, for so many more folks who actually need help in life, then any good that will come from giving a few extra grand to a sports department that already brings in a hundred million dollars a year or so.

I'd feel personally guilty for every dollar I gave to such a "cause" instead of putting it to better use.
