This is basically true, but there are large differences both in volume and nature. It is likely true that Chinese government hackers have compromised every large western corporation. In 2010, when Google went public about its own problems in this regard (what they dubbed 'Operation Aurora'), every competent IT security department lead was nodding his or her head because it matched what they had themselves seen.  Most companies keep these breaches secret unless personal customer data is specifically stolen.

There isn't equivalence. I agree it is concerning that CSE has appeared to be hitting friendly nations for economic reasons (noteworthy: the targets were government, not private), but whatever the reason, the intel is not finding its way to corporate leaders as it does in China. The fact that we can only speculate about CSE's purposes is because that kind of information is locked down so tight.
