Yes, this could all be lies, but so could literally anything anyone says. Either you choose to live as a recluse in the woods with no technology, or you choose to trust at least some corporations. That might mean trusting your search engine, your cell phone company, your car manufacturer. Heck, you're trusting your ISP right now not to do a MITM attack on you. The natural conclusion is that you should use strong encryption in everything you do. At this point, there is one company spearheading this to get it into the hands of consumers who don't know any better.
Again, I realize Apple isn't blameless, but there's an awful lot about their recent actions to show they are making decisions based on what is best for the consumer. I think that's a good thing, and it's hard to imagine why someone would argue against it.
