I think it’s very typical of very casual and exploitable users to have product names deeply connected with a certain activity — eg. using Google or Zoom as verbs — and “cloud” storage companies would like them to think of their brand name as the main storage area on their devices (and certainly not as just rented space on normal drives in a big room full of someone else’s computers), and I think they are and will be successful, and these users won’t think of them with generic terms like “filesystem”.
