There are some reasons to be skeptical of Blockstack in particular. They make a lot of claims, pump cash into apps without disclosing it's actual source (they claim it's from sales of a subtoken, but aside from a blog post, I can't actually find any evidence of that) and in general have built a JS heavy library that is setup for easy code injection.
None of these apps need a blockchain. None of these apps gain any benefit from a blockchain. Just, I dunno, don't use a giant universally observable blockchain that suffers from the majority issue in order to store private data? Seems easy enough.
