Why don't they let gizmo function, and work like before?

There is no reason to cripple gizmo like that.

They could just rename it as Google Gizmo or something.

I hate it when a company gets baught, then the customers get shafted. And then the company decides to destroy a good thing. The easy solution is to provide two solutions in parallel. Not everyone wants to use 'google talk', and are happy with gizmo. two brands = more exposure.

Sounds like somebody has a hobby.

As it goes... "Google is the one..." :)

Buying one company a month? When does Google become a monopoly?
