Even if you put aside concerns of possible algo bias towards TLDs Google owns, there are other concerns.
I think he has a point. Or doesn't he?...other critics of the move, including Irish blogger and domain registrar Michele Neylon, say they have no argument with either Google or Amazon — or any other company, for that matter — controlling their own domains, such as .google or .amazon or even .gmail or .kindle, since those relate to trademarks that they have as a corporation. But why should Google be allowed to single-handedly use .blog, asks Winer — who helped pioneer the medium through his Userland software:
"What if the name was created by an open source community, without the financial resources to mount a challenge? I have some standing there, because I played a role in establishing blogs. How does Google get the right to capture all the goodwill generated in the word blog?"
What about .cloud or .news?
