I actually agree, I own my computer / OS and I should be able to do what you’re saying (install and break things). But Microsoft is a trillion dollar multi national corporation and I am certainly going to give them grief about this because I owe them less than nothing, let alone any good will.
This is funny, but I think stereotypical vampire lore still stands. I think it’s only direct sunlight that is an issue. If a vampire stands in a room with an open window, but off to the side, they’re generally considered fine. If light reflected off a wall is ok then why is the moon not?
