Anyone can "build" a company from scratch.... But it takes a lot to build a successful company from scratch, which isn't what Fridge did here. I mean, I know not everyone is a startup founder, but the costs and barriers to being one is pretty low these days... just start a website, say you're doing something special, and you can call yourself a "founder".
That's still missing the "and have it bought by Google" part. I know how low the barrier to entry for founding a company is - hell, I've done it myself - but there's still a fairly high bar to being acquired, or even aqhired.
