For as long as money is instrumental in determining the allocation of resources and power, the goals of commercial entities (and their propaganda) are inherently political in nature. By advocating for their own profit they are advocating for a certain resource distribution strategy that they want as many people to get on board with. What Twitter is really saying is that they are fine with political messages, just not from institutions and by means that are typically associated with democracy: for as long as you only represent your self-interest rather than constituents and members in a democratic sense you are free to propagandize as much as you want. The result is highly political, just directly anti-democratic.
