I find stuff like this very depressing as it just reinforces the feeling that pretty much nothing does what it says on the tin
I know what you mean.
I wonder how these products get made.
The marketing people create a great pitch for a product which appears to be 'cobbled' together by people who are not rigorous enough in thinking through all the possible workarounds and hacks.
As alluded to in the comments on the article, it would be sufficient to hide data from average users but anyone who might be after your data is more than likely NOT an average user.
The issue for me is that it adds to the erosion of trust in any products/methods that claim to be secure.
I am not an encryption expert, so I, like many, have to trust claims from manufacturers when I purchase kit.
I cannot afford, in all senses, to find out the hard way that my security is just a false impression based on marketing campaigns.
You get the impression more and more that the conversation was more like 'Security is making the News all the time. We need a secure product range to sell, Yesterday !! ..... Quick hack something together so we don't miss the opportunity. Don't worry about testing it too much we don't have the time.'
I hate being treated as a mug by Companies & Sales people.
