If you design a system such that you cannot differentiate people from corporations and bots and that’s your defense for calling all of them “users”, you’ve designed a system that doesn’t differentiate between people – who are mortal, have feelings, can feel pain and be hurt and who have human rights that must be protected – with the very entities that oftentimes exist to exploit those you so readily lump together with them.
Design for humans. Call them people. All else is secondary.
