Not really - what they’ll do is put in the date tag some much more recent date than the date of publication to try and push the content towards search engines to make it more likely to show up, lie about stock levels (say some product is in stock in the metadata, but say on the page it isn’t in stock), cram keywords into metadata, stuff like that. I don’t think it’s really an improvement.
They just eat the other humans remains, duh!
