The answer to number 1 is an easy "no" because trade secrets are crucial to just about every industrial sector and an algorithm is clearly a trade secret. Even the food industry allows trade secrets -- the secret Coca-Cola recipe is not printed on every can. Even the Pfizer and Moderna vaccines have proprietary stabilizing agents in them. As much as it sounds nice, the outcome would be vagueries like "we use algorithms to select the content we think you'll find most interesting based on your past browsing behavior".
