You've got me sucked in now. So let's assume that I work for Gitlab, and I host all of my side-work / personal projects on Gitlab. Do that mean that those projects are effectively using "company facilities or assets?"

Usually "using company time/equipment/etc." are viewed as things that you obtained via your employment with the company. But what about things owned by the company that I would have obtained via the same channels as any other customer. Does Oracle have a claim on IP created using a piece of Oracle consumer software by an Oracle employee?
