This is an interesting take - I hadn't really considered it, but on reflections Google's more academic claims are hyped up in a way that IBM doesn't seem especially guilty of. Some of their image recognition breakthroughs have been truly remarkable, but I agree the claims are a bit out of line.
I think I was probably put on edge by the Watson ads not just because of their scope (the Skype thing is similarly inaccurate) but because they conform to a very specific pattern of AI over-promising that I've grown to hate.
To a lot of nontechnical (or even just non-CS) people, strong AI is synonymous with Samantha from Her. We've been seeing people mistake existing tech for that since the 60s, when people were taking ELIZA seriously. Cue Cleverbot, Siri, and most obnoxiously Eugene Goostman (you don't get to claim you passed the Turing Test by convincing 30% of English speaking observers that you're a Ukranian child!)
So I look at the Watson ads and see exactly this pattern at work, but worse than ever. Most people know by now that Siri and Alexa are just voice assistants, and as good as the ads look no one is really claiming otherwise. The Watson ads, by contrast, throw around "cognitive computing" to imply real understanding, and then air scripted exchanges that are simply false, rather than selective. Worse, they're doing mass-market ads for a developer-only product, so viewers won't even try it out and see that it doesn't do what's being shown.
It may not be the worst on an overall-inaccuracy level, but I get twitchy when I hear people respond to discussions of strong AI with "Oh, basically what that Watson thing does?" And I do hear that, somewhat regularly. Crappy product hype is annoying, but I really wish we could stop telling people we've built real intelligence when we haven't.
