You say it like it's so easy. It's not. The reality is many (maybe even most?) articles - even ones from incredibly openly biased sources - do this. It's often difficult to make many meaningful attacks on a proposed law without mentioning what the intent is.
Unless it's one of a few already highly-covered issues with fundamentally irreconcilable subjective issues where you can pretty much recall all that context with a few words... you have to say what the heck the proponents of the law say it'll do to actually attack it.
However you don't seem to find that balanced. I don't blame you. I don't either.
The problem is the arguments made cannot be equal. They are not the same thing. Even a good faith attempt to make a completely neutral article will very often fall short. Even if the author thinks they did not, others will.
The only 'balance' you can really have is a false equivalence where nothing matters because it's all the same anyway - so why even write an article? It doesn't matter what happens.
It’s not as complicated as you’re making out.
If I read an article about how a proposed law is bad I’d also like to read an article about how it might be good.
Not rocket science is it?
