Late stage capitalism at its finest. Cut-throat competition becomes oligopoly becomes monopoly. John D. Rockefeller figured this out about 150 years ago.
You can always buy NUAN stock. I'm serious, this isn't hyperbole or sarcasm. I won't buy a "merchant of death" like Philip Morris, but I'm going to check out Nuance. If they really have become a monopoly, perhaps there's some money to be made by investing in them.
Yes I know it sucks, and in an ideal world you have every right to be "pissed off". But in the real world, you'll do better to remember the slogan: "if you can't beat 'em, join 'em".
I personally am much "more pissed off" at how companies like Comcast, who are "natural monopolies", have been extracting ever larger "monopoly rent" from everyone. They should be much more tightly regulated than they are.
