In case of things like YouTube I assume that everyone just knows it and directly types youtube.com or opens the app instead of googling for it.
Or maybe I’m wrong and nobody types urls directly into the browser anymore?

So if I ship a version of vscode with a few extensions pre installed I can call it an ide?

You could call vscode a “DIY IDE Building Kit” because everybody is using it that way.

After you put all the extensions together you basically got a fully featured “IDE” for most languages out there.

Nobody I know uses vscode like a simple “code editor”.

What is space exactly?

I don’t know much about law but I assume that you can also be liable for things you don’t own.

If I rent a car I don’t own it but I’m in full control of it so I’m fully responsible if I break any laws with this car.

I think one could argue in a similar way for Xitter accounts.

There’s still a chance that a monkey will type it on the first attempt. It’s just very small.

This person takes advantage of people who are unaware that they could just get it for free as well.

However, if this person is putting in an effort to sell this item (like advertisement or creating a platform to distribute this item more easily) then I don’t see anything wrong in charging money for that.

With software there would be infinite copies of that free item for everyone to get. So the dick move is to sell it to people who are unaware that they could get it for free.
