Wow Prudential and Ford (if USP is supposed to be UPS, that too) are the odd ducks. At least the others have the internet as a core competency.
My guess as to the answer of “why” is power and leverage. It’s the same as nations claiming physical land. “Maybe we’ll need it, maybe we won’t. But either way, now it’s ours to decide.” Writing that out, do they own those? Can someone take those back?
