This is incredibly fascinating. The implications are at once horrifying and magnificent. In the first case, it opens all data that's held by a company licensing it out to decrypt or hand over the data (the point of technical ability is fair, although I don't trust that Apple specifically have express access to everything. I don't know the encryption methods being used or how they're applied to Apple products). That's obviously awful for the end user and especially casual users. On the flip side, you have that this drives more people to FOSS and hardware, which is always dandy for personal rights and the security industry, but even more importantly, it incentives companies to sell their software, or at least license it more reasonably to remove themselves from litigation (or worse in most of their cases, bad press).
