In what fantasy land do you live where an essay company would (1) ever be "questioned" by a university or (2) "give up" any information about its clients? Universities don't have any legal authority to demand any information from private companies.
Make up your mind already: Is your problem with ET that they DO prohibit plagiarism or that they DON'T? You've started threads complaining that they should be more vigilant
against plagiarism and now you seem to be implying that it's a waste of money to buy essays unless the company DOES allow plagiarism after sale. Which is it? If you're against plagiarism, what do you care about students who plan to misuse the product? If you support plagiarism, what's with all your complaints in other threads that ET doesn't do enough to counter it?
Only an idiot would try to maintain both positions simultaneously.
Reputable companies inform their clients what uses of their products are permissible and warn them about impermissible uses. As a practical matter, no essay company has the means to know what students do with their work. They include the prohibition in the contract as a deterrence.
It is inconceivable that any essay company would "take legal action" against a copyright violation that doesn't involve
selling their property. For students who use the product properly, they can definitely learn how to structure an essay, write properly, and research effectively from it.
