(The Scott Trust does not make much of a difference here. A business can have such a way to remain free of outside pressures but still be a straightforwardly commercial company.)
Open and transparent as possible is still not open or transparent.
There is no way to verify that what they published is actually what is running on their server... so publishing a repo means nothing in regards to "openness and transparency," for this or any other website. All of them are proprietary black boxes as far as the end user is concerned.
The alternative exists that they really know the more strident bits of conservative media are fake, and just don't care. And indeed, delight in it because of its outlandishness.
A recent, concrete example of this is all the breathless reporting about Chinese camps containing a "million" Muslims. The story was complete hogwash [1] that was breathlessly hyped by every American news organization. The Guardian provided the most restrained and actually facts-based reporting by far. There are plenty of other cases like this -- see similar examples involving Iraq and Iran.
I could imagine how not being fully committed to the pro-America hegemony might be confused with being left-wing though. It's the sort of thing where the problem is the problem, as they say.

This is not journalism. The whole article quotes a paper published by a neocon think tank with ties to lobby groups payed by wealthy corrupt under investigation by the (Romanian) DNA. The article even hilariously uses references to recentnews.ro, long proven a fake news site, part of a network of fake news sites that launched the infamous "Pope shocks the world endorsing Trump".

I long for a source that gives solid middle ground information and analysis.
Usually the Guardian opinion pieces tilt to the left/progressive viewpoint, but not always. This is something I appreciate, not being always stuck inside a bubble.
The second link offers a summary and analysis of an interview of Assange, the original piece is linked, and while I didn't read all 3 articles completely I didn't see any massive distortion jump out.
Are you talking about the articles labeled "Opinion"?
