I interned there a decade ago and still have 1TB free from that; I would have switched away a LONG time ago if not for that. I hate how sending anybody a link spams them with a million pop ups, i think the intrusive ads almost make it seem like they need a dropbox account to view my file. Sending files to my friends is embarrassing, sending files to my grandparents impossible.
If you work a company with a large monorepo, you often want to vendor all third party dependencies in the tree — you don’t want the build of this massive repo to be down because one of the five package managers it depends on is down. And if there’s a single vendor folder used by all projects, you’re certain that all parts of the tree are using the same version of the external dependency.
