My relatively-lower concern regarding the practices of businesses is that I can understand and predict their motivation—to extract profit from me. With the government, they are not satisfied with merely obtaining money, they also want control over the lives of their population.
Using its "monopoly" the state primarily grants the major part of control over your life to yourself. While I share your concern that the state still is trying to keep a lot too much of it by itself, I do not trust companies a bit more. They won't let you the smallest bit of "control over yourself" if they have the chance to get and monetize it - up to the level of selling your physical extents. Corporations tend to act like dictators if they are allowed to and they have proven that -not only during the age of Manchester-capitalism- wherever they could.
ATI once made really good graphics cards. After the Nvidia GT that my last workstation came with broke I bought a recent ATI Radeon. It was quite a disappointment.To be honest it was about the worst piece of crappy video hardware I've ever seen- and I've seen Voodoo I (the one you had to install additional to your primary adapter) to III (the one you wouldn't get updated drivers, because they went bankrupt)
"Luckily" it broke after 1½ years. I am not going to miss it.
So what new, shiny features do you expect an e-mail client to provide? Don't fix it, if it's not broken. Thunderbird, Evolution, claws are all fine. The only differences are the way they will archive, sort or filter mail - and more or fewer things not strictly email-related.
What this country needs is a good five cent microcomputer.
