Firstly the title "What if we prove them wrong". Of course Lenore means that to be read as 'we' the public but actually Lenore is a Guardian Editor and big media insider.

As the the chaotic way facebook has blocked sites it didn't mean to, that's just because this law's definition of media sites and how to identify them and know you have to pay to link to them is a mess.

On the one hand Lenore is saying Facebook is finding it incredibly hard to block news sites without blocking all sorts of stuff unintentionally, so it's clearly a hard problem facebook is having major problems solving. On the other she's saying blocking news sites was easy and so they should be able to block harmful content easily too. Doh!

It seems it's literally not possible to argue in support of this new law without contradicting yourself, at least I haven't read one yet that doesn't, they're that dumb. Heck I don't even use or like Facebook, I think they're scumbags, but that doesn't mean imposing stupid laws on them or anyone else is ok.
