Well sure, and hopefully progress will even speed up as people are forced to think about the fundamental insecurities of web toys and realize their hipster "disruptive" day job is actually just the status quo. But that doesn't mean things are suddenly going to change overnight, and the noise over these revelations will have long died down by the time privacy systems become popular.

The direct point I am making is that privacy preserving tools necessarily run on a user's computer completely under their control and need to be open source to be trustable. Which means they're incompatible with business unless you want to fall back on support and custom development. So they won't be promoted or purposely developed by established companies such as Yahoo, or VC-funded startups looking for a big exit.
