The problem is that it doesn’t matter if they publish how they came to their conclusions if how they come to their conclusions is nonsense. Your link is a perfect example. In the bias section there is a paragraph consisting mostly of cruft followed by two sentences attempting to justify a left rating:
One opinion piece on green hydrogen is apparently enough justification for MBFC. I actually can’t even tell if it’s an opinion piece because it doesn’t seem to have the author’s opinion in it anywhere, it’s quoting reporting from elsewhere and a letter.
Doesn’t that seem pretty paper thin? I don’t think they even bother referencing any of the categories from their own methodology in this one.
I feel like I’m the only one that has actually read any of their bias justifications because after you read one I don’t see how can take them seriously at all. Maybe I’m missing something though, or I’m just going mad because lots of folks keep referring to MBFC as a serious organisation.
