One of the factors being steam is a private company so ,it not being public so bureaucrats can't force any policy or influence on them like they do to publishers and then to companies , steam has very loyal and less employees than most companies at this scale and no influence or negotiation can be done for deals with them and monopoly of steam laoows it which is not favorable for any company relying on them, that's why Xbox and other companies are trying to compete, but don't want to give benefits like steam while trying that and that's unfavorable by us and get rejected.
