Surely anyone with any sense will have known from the outset that a large commercial organisation pumping money into a free OS wasn't perhaps doing it completely altruistically? Just as with facebook, what initially was a freebie now has to make a return as a business proposition.
The beauty of LINUX is that this isn't a problem - simply hop distros, even a newboe should be able to work out how to do that these days if they got as far as installing ubuntu in the first place. I think Canonical have done a lot to raise the profile of LINUX, this isn't a massive intrusion and it can be disabled. I'm not going to get too het up about it, that's the joy of choice. Personally I'm platform agnostic, I run Win7 on my desktop, mint on my 17 inch laptop, ubuntu on my netbook - I'll upgrade the netbook to latest when it's released, turn the search feature off, and if I still don't like it I can install another debian based distro without any significant hassle.
I can see where the privacy advocates are coming from, but given the options available from my perspective there's not much unexpected to see here, and to make out there is is simply slinging unwarranted mud at LINUX as a whole, isn't it? What am I missing?
