This website is not a tool - not really.
Your keyboard is.
Censoring AI generation itself is very much like censoring your keyboard or text editor or IDE.
Edit: Of course, "literally everything is a tool", yada yada. You get what I mean. There is a meaningful difference between that translate our thoughts to a digital medium (keyboards) and tools that share those thoughts that others.
A website is almost certainly a tool. It has servers and distributes information typed on thousands of keyboards to millions of screens.
