Public companies have to account for the shareholdres' expectation of, well, making money (and more money, and more money, and growing the numbers as much as possible). Shareholders have some degree influence on how the company works, depending on how many shares they own, e.g. they can vote for the CEO. This usually leads to the company to introducing more aggressive ways of making money off the users/customers, enshittification, etc., as it has to satisfy the shareholders and not so much the original customers.
