If you travel abroad you must unlock. No 4th amendment for you.

Yes it's bad that the government overreaches, but it is also bad for your mental health to worry about it.
The majority of people walking in the worse neighborhoods of LA or Chicago never have a single crime happen to them. But that doesn't mean that it's safe to go in a bad neighborhood - and it really doesn't mean it's safe to go there wearing designer clothing, gold watches, diamond rings and wearing your Apple VR device.
The same is true for travel. It's perfectly safe for the vast majority - but it's very important to be aware what may make you a target and what can happen to you if you are. Tens of millions of people visit the UK or China every year with no incident. But if you're a public active supporter of Palestine Action, or an active demonstrator against the CCCP respectively, be aware that you personally face a real risk from this travel, and your devices are actually very likely to be searched at those borders. Vice versa though (anti-CCCP activist traveling to UK, PA activist traveling to China) is perfectly safe, though.
(CCCP = Union of Soviet Socialist Republics...)
Though I should note that this would be the "SSSR" since I was clearly using the latin alphabet, even if I had chosen to use the Russian name of the USSR.
>CBP only searched the electronic devices of 55,318 international travelers,” the agency wrote, or 0.0013%.
would suck to be one of those 55 thousand people. I've never been bitten by a shark but I sure care about people that have?
It seems more like they're trying to determine that it is in fact a laptop and not something resembling one.
Edit: now I am gleefully thinking about how I would craft my decoy desktop persona. What gives me the most effective non interesting profile.
