Ok, firstly, I think it's great that so many people are engaging on issues of privacy and at least trying to help folks understand how to mitigate their risks in these situations. Something I think that is getting missed about all this is that a lot of people are being very US and techno-centric when they create these articles. Security when travelling is about more than just digital issues.
Doing something like this requires that you consider the risks of your phone seizure versus the risks you may face without your primary smart phone. If your an activist flying from London to D.C then fine. But what about if your an activist flying from D.C to the D.R.C and back - then your threat model changes from potential TSA problems to physical security threats.
For just one example of this, let's say you ask people to ditch their phones and take a burner because of a potential risk at the US border. Now you have removed one of the best devices for the person's physical security - a smartphone that can update people about security alerts, about local news, weather, disease risk, riots (e.g the stuff we put in the Umbrella App dashboard - shameless plug -> https://www.secfirst.org), share data amongst groups of people on the ground, can send GPS alerts in a emergency, can help them navigate if there is a problem, has a flashlight on it in darkness, has access to emergency contact details, insurance information, medical data, nearest hospitals etc. Now, your relatively low likelihood/low impact potential digital security risk at a US border has overridden the low/medium likelihood but high impact physical security risks...
Ditto it's important to thing about basic tactical things like that people are lazy, data is expensive and they will often not bother to restore the most important contacts and information that they may need when they travel, which can be a problem in an emergency...
Again, it's great to see people engaging on security issues but please be aware of the threat model, context and consequences of what you are trading off.

I'm confused about why you're implying a burner/temp travel phone can't do these things. You can get a cheap & fully capable android phone at best buy for $40
