well it is true Google is worried about a combine co of Microsoft and yahoo, it would hurt there money tree, but in the same breath I sure do not like seeing Microsoft get any bigger, and have more control over my computer

Google’s points on the maybe/maybe-not acquisition are all valid.

If you, the regular ol’ internet user, use a PC and Microsoft acquires Yahoo, then you could very well be a user that:

Uses a Microsoft operating system to get to the internet
Uses a Microsoft web browser (IE) to browse the internet
Uses a Microsoft service for all instant messaging
Uses a Microsoft service for all e-mail
Uses a Microsoft service for all your photos
That’s a big, big chunk of stuff.

A bit too big.

using a Microsoft-owned service or product for every ounce of your computer usage is scary. Everything from IM to OS would be branded with M$. Every time you click on something, their shareholders make a bit of revenue.

The same goes for e-mail users. The article you cited says that there is very little real numbers. There isn’t a real way to tell if those are active account and/or if the are all legit.

This is a good article that say that anti-competitive behavior is viewed in the eyes of the consumer not the corporation.

Google is currently the most used search engine and I assume that a lot of the revenue comes from those searches.
