Google = Microsoft 15 years ago
What rubbish.
Google does VERY WELL control who visits their website. It PAYS several browsers to have Google as the default search engine in the browser. This is no different to MS paying computer manufacturers to install Windows as the operating system. No one is forcing anybody to buy a Windows PC. They could all go with Linux or a Mac. But choose not to. Just like most web users choose not to change their browsers default search engine.
What then happened is that MS became so big that you effectively HAD to have Windows PC if you wanted interact with most other businesses. MS Office being the main reason, but there are others. Then MS started pushing it's own software/services preinstalled onto it's Operating System which I personally thought was great. No need for crap like RealPlayer. Just use the inbuilt Media Player. Or if you want, you can install something better (VLC perhaps). I don't think RealPlayer thought that. Are they still around? MS paid a small fine for that, but they didn't care, it just meant Bill G's estate was a few acres smaller.
Well, it's IDENTICAL with Google now. So everyone now uses Google because it is the default search engine. It is also the best, probably. But we'll never know because, well, anybody trying to compete with Google on search is either a fool or Micorsoft. Now Google start pushing their services through their OS, sorry search engine. Want to compete with Google Maps on Google's search engine? Bad luck. You could try competing with Bing's Map (or even Google Maps) on Bing, but nobody goes there anyway so not much point. This is no different to trying to compete with Media Player on Windows. Bad luck. You could try competing with iTunes on a Mac - if you're a masochist. In the end your left with competing for market share on the Linux platform. Except those guys don't like paying for stuff.
I for the life of me can't see why educated IT professionals can't see that Google is doing exactly what Microsoft did 15 years ago. Google IS the OS of the web. What do most people do when they turn on a PC? They go to the browser and do a search. Which takes them to Google.
Now, I am not saying Google are evil. No more than any other coporation for sure. Nor are they infallible (in fact I see them being a lot less important in about 15 years time - they've missed the boat on social networking for a start), but they ARE a monopoly in the same way the MS were 15 years ago.
