It is liberal based and they call that the neutral point of view. They give away a majority of their funds to the Democratic party. I stopped donating to them when I found out.
I was also stopped donating, but it was due to a combination of finding out their financial position and that they have a media whitelist. So different to the open culture it started with.
Originally it was a porn site that changed to an encyclopedia. They reject neutral third party sources even if they claim to allow them with the whitelist and blacklist.
