"zoom" is a verb (also sometimes a noun), "Zoom" (the company/product) is a noun. I agree that "Zoom" as a noun is already confusing as capitalization isn't a very reliable way to differentiate words, but "Zoom" (the noun) being used as a verb that is completely different from "zoom" (the verb) is a whole other level of confusion on top of that. For citations, see your sibling comments. And besides, confusion clearly wasn't my main point.
