The license literally says "you can't use this". How are so many people confused about the license in this thread?

Based on what law/authority?
Copyright law forbids making copies, derivative works, etc. Not using things. You're allowed to read a book without a license.
Moreover copyright law makes an explicit exception for the copies required to run a computer program on a machine that aren't used in other ways (i.e. copying it to ram/registers): https://www.law.cornell.edu/uscode/text/17/117
The author may say "you can't use this", but it is not clear to me that he has any legal authority to do so.
Simply reading the words "Don't use it" does not bind you, because there is no grant of use; there is no offer or exchange of value, so no contract has been formed, and the statement is at best advisory. It is equal to writing "All rights reserved", which is to say, you retain whatever rights pre-existed under statutory and common law, such as right of fair use and so forth, and anything due to Github's ToS.
Engineers often fall into the trap of thinking the law is a programming language. It isn't, mercifully.
If you stole a copy of Microsoft Office on CD from a shop (back when that was a thing) it seems clear that using the software would have been a copyright infringement because you wouldn't have been the owner.
In this case you have the right to download the software (via the github agreement) but how does that relate to ownership and the legal exemption? I've no idea.
