Based on what I've heard anecdotally from e.g. freelancers providing services to large corporations, that ship has unfortunately long sailed.
There seems to be a huge spectrum, with "email an invoice payment instructions to the right department and you'll be paid, whoever you are and regardless of whether you provided any service" on one end, and "consider yourself lucky if you saw a cent at the agreed-upon time without having to resort to small claims court" on the other.
Obviously, it's much harder to pull off the latter when the payee is a huge corporation themselves and/or has leverage in terms of being able to cease providing ongoing services.
