Any other company? You've named three. Truth is enterprise grade companies that serve the business market and don't give their products away for free or participate in a race to the bottom typically don't do this type of thing to the degree that google does. Perhaps the companies that do (including parts of msft) are those that deal with developers or consumers which apparently are more likely to not complain to much (other than to whine online) when they get the shaft. The stereotype, unfortunately, is true. At least that is what I have found.
Also, and this is important, there is the benign neglect phase where they simply keep the product minimally working but don't spend any time to improve it (like google voice).
