Fun fact: the shapes of the letters in a font can’t be copyrighted, but the file that defines a font can. The name could be trademarked, though, so even if you redrew a font you might have to give it a different name. If it’s not trademarked, though, that’s how you end up with several companies having their own version of the same font.
I’m thinking at those prices this is probably intended for corporations that absolutely need a readable display in bright sunlight areas but don’t really care about refresh rate or color depth.
