The article says "internet", but it really means "the HTTP based family of applications that use the internet". Sometimes a customer gets me by mistake when they need help because "their internet is down". I start to get mad because of self contradictory statements, but then I remember that they really mean, "my web browser stopped working". (You can tell I'm not really tech support because next I try to find out what browser they are using, and they are never able to tell me. Which means they are using IE.)
Having cleared that up, I can only see consolidation of HTTP applications under some super googly company (perhaps one the article writer envisions heading) as making things worse. I suggest that clutter in your web browser is not much different that clutter in your house. Get a book on Feng Shui or equivalent and start deleting the stuff that isn't helping you (making you happier, needed for work, etc).
P.S. I discovered a very important, but little known principle of error page design. If you put something in giant type at the top of the page, no one reads it. It you put it in little bitty 6 point type at the very bottom, everyone will read it. Even if they need to use their magnifier app. I can't explain it (it must have something to do with lawyers), but now that I know, I save a lot of frustration by putting the most important message in little bitty type at the bottom. (I still leave it at the top in big type also in case any old fashioned types like me see it.)
