This won't be popular to say....
But he's kind of right tbh.
Politicians are, in theory, accountable to the general public. Apple/Microsoft/Google/whoever are not accountable to the general public; they're only accountable to their own shareholders. So yeah, it's meant to be the politicians' job to decide on this, not Apple/MS/Google - even if Apple/MS/Google's decision is better than the one that the politicians come up with.
The fact that US politics is hopelessly delinquent and makes little effort to follow the popular will (to the point where Donald Trump looks electable to a significant portion of the population) doesn't really change the fact that private corporations aren't supposed to be in the business of deciding what the law ought to be. If Apple decide that they don't need to follow encryption laws, then they may also decide that they don't see why they should follow antitrust laws, or health and safety laws, or bother filing honest accounts.
Of course, we might point to the fact that Apple/MS/Google/whoever seem to spend an awful lot of money lobbying to get a say in what other laws are. But I'd say that it'd be better to make that particular practice illegal (since the US political system is now basically just legalized bribery) rather than pointing to one problem with the present system and using it to justify allowing corporations to make up whatever laws they happen to fancy following today, tbh.
I think that the US government is hugely overstepping it's bounds here in a dangerous and unconstitutional manner which threatens privacy on a global scale, and I think Apple are firmly in the right by saying that they shouldn't be made to help crack encryption on personal phones... but just because their motives are 100% right doesn't mean that the principle of refusing to do so is also right. It is ultimately the job of politicians to decide this. If you don't like the answer that those politicians come up with, well, you can vote to replace them every 4 years. Why not try doing that instead of continuing to vote them in and then complaining that you hate every choice they make.
