I have no problem paying for good mods but I've not allowed Skyrim to update because I'd have to go through hundreds of mods to figure out which ones the update broke and I'm just unwilling to do that .
It's difficult to tell but as a long time glasses wearer I can tell you it's probably just the sweat/oils of your head reacting with the metal of your glasses. You might be able to clean some of it off but it's likely just going to be like that going forward.
They've already done that previously, years ago I had a 'notebook' with a version of Windows 7 where all options were ridiculously limited unless you upgraded. Would never have bought the thing if I'd known.
Could be loan payments, repaying investors, taxes ..
