Why do production companies like Warner Bros & Universal etc. Accept no film and series ideas?

Because of curiosity, I was on the websites of production companies such as Warner Bros, Universal Netflix, etc. To see if you can send your film ideas, but each one said no ideas would be accepted and the ideas would not be read. Is there a specific reason for this? I know that such companies get a lot of ideas but at Netflix and Warner Bros an agent or lawyer is required before ideas are sent and other companies do not accept… But what if the idea changes the whole world of film? XDD

Most of the ideas of ordinary people are just junk.

Who should read and edit them all? How much time and money do you think that is?
