Just don't cut/paste whole articles. You can copy a few sentences so long as you make comments or criticisms on it. The idea behind fair use is to further society by making it legal to criticize the works of others. If scientists could not report the findings of others they could not disprove anything, and no progress would happen. Just because somebody has paywalled or copyright all over their material, IT IS NO FUCKING BLOCK TO FAIR USE. They can say, "Copyright xxxx, all rights reserved, do not reproduce etc etc etc" Fuck that shit. You can STILL use parts of it under the fair use clause. Learn it, know it, live it...
