> cities must let developers convert office buildings into housing This is an Activist piece - not an Analysis piece. You cannot trust facts reported in an article that's advocating change. It cherry picks a number of facts in order to further the arguments.
There's zero reason why an article advocating for a change can't also contain trustworthy facts. I'm not saying this article is a good example of one, but I wouldn't follow "You cannot trust facts reported in an article that's advocating change." as a general rule. Pretty much every article advocating for a change is going to include facts, but that doesn't make them all untrustworthy. Advocating for something in an article doesn't require the author to ignore everything that doesn't support their viewpoint, or lying/misleading, or cherry-picking.
Identifying that an author is advocating for something should cause you to be on the look for out for those types of things (that's just critical thinking), but they shouldn't be assumed and the article or the facts it contains shouldn't be immediately dismissed as untrustworthy or wrong based on that assumption.
