I thought that was what the warning was for. The original cartoons were great and still are but I don’t see them on tv much - presumably for the obvious reason.
I think its more a case of Amazon owning the broadcast rights to classic T&J in the UK at the moment. I think the later series are covered under a different agreement. The old ones are available on Amazon Prime.
I was well into adulthood before it occurred to me that the human in Tom and Jerry cartoons was probably a domestic servant.
