I guess the only thing is that some people (e.g., the OP) feel that the DoJ should be going after other areas first, like cable/satellite and wireless providers. I think the price fixing among those companies is much worse. But I guess they're going after a case that's easier to prove.
Yep. Easier to prove, is also a major industry/business, and very easy to fix and help out consumers. And far more shady/illegal from the corporate side of things.
When it comes to the communications industry, there is so much shit wrong, the DoJ can hardly sort it all out in one fell swoop, as the case seems to be for ebooks.
I'd love for the FCC and DoJ to sort out all that is wrong with the communications industry and do something great for the consumer, but it's difficult to really provide examples of illegal activity. They are screwing us over, but for the most part, doing so lawfully. It's one of the many ways we are forcefully penetrated from behind if we wish to be granted access, and basically the government can only say "if you bend over and relax, it won't be as bad." :\
