>Here, though, they're suffering a huge PR backlash, which I suspect is because they're out-marketing the work of passionate amateurs and academic researchers instead of e.g. big phone companies.

From my perspective, I'm more frustrated with how they don't seem to be producing anything. They just release a PR video every year that is about the same as the PR video they released the previous year.

Until they actually produce something useful, I have no problems referring to this stuff as vaporware.
