Misprediction? They are simultaneously surveilling everyone in the world and are getting nothing out of it. Confident statements from the administration are no longer worth a dime.
If they're not worth a dime then don't mention them at all. If they're worth something then they need to be discussed "seriously", as the blog post itself preaches. Not mischaracterized, and not used to mislead readers about their contents. All the arguing you're doing needs to be in the blog post, not here.
