Having Google enter your space must be one of the most crushing things that can happen to a small company. The feeling these guys felt when they saw the announcement must have been mortifying. Even if you have a superior product, like LiveNinja says they have, Google will outmarket you by so many orders of magnitude you just disappear into nothingness.
I hope fellow entrepreneurs dont ever get discouraged when they see larger companies follow them on the same trail. It means they are on the right track more than anything else.
Dropbox didnt get discouraged and neither should any other startup.
In this case, LiveNinja was first, Google copied it, apparently building the exact same product.
So, I'd read the original post as "please buy us" as well.
The rest of the stuff I can think of is either competing but not dominant (phone OSes, browsers), or bought as a winner (doubleclick, youtube). They don't seem to have honed their Microsoft-ish emulate-and-destroy skills.
He's probably not bluffing that Google moving into your space is a good thing for your company.
Google has pretty much unlimited resources and an army of bored overqualified engineers. They can literally take any successful online business, implement it themselves, and push it forward with their search engine.
It's not illegal, I know, but it is unethical.
