What you say of its fundamental goal can be said of any other newspaper or any source of information.
The only solution I can think of is to somehow promote the use of non-profit providers, but I know of no good/usable ones in either case. For news, there are individual, independent bloggers, and for social media there are closed chat groups or something, but that's about it.
I don't know if there is any solution at all. I expect both sides to maximize spiced up news delivery for maximal attention and devotee base. At equilibrium, we may have these equally weighted strong groups which may randomly win election by small margin each time. This might not be too bad because over longer term all decisions and laws would be averaged out over two opposing philosophies resulting in overall centrist and balanced system.
