I think this is bad advice. It's probably better to upload any data you really need to a server as an encrypted file then download it upon reaching the destination, and taking a pretty blank phone. Journalist organisations could even prepare android images suitable for border crossings. It would be a hassle, but better than having sources exposed.
Saying "I don't know what the password is" probably isn't going to be considered a valid response.
In general I think folks should run their own instances of !gnusocial if they can. That reduces the problems of administration and makes the fediverse more robust to failures or censorship.
The wording about commercial activity indicates that this is more aimed at the silos than at GS, but if this passed then they could designate GS to be a "regulated social media platform" at leisure and create the new crime of "running an unregulated social media system".
Also, UK politicians are idiotic enough that they would think this was a good idea. Even under Corbyn, the authoritarian nature of the Labour party shouldn't be underestimated. An obvious indicator is that they voted enthusiastically for some of the most invasive spying powers anywhere (the IP act of 2016).
@captainfrosty @mcscx @monsterbater as always it depends on the threat model, but I would avoid VPNs and just stick to a Tor browser as much as possible. Also use Orbot/OrFox on mobile. VPNs typically aren't secure and if the government is your main threat then they'll hand over any data they may have about you. Primarily VPNs are used for censorship avoidance rather than privacy.
@bobjonkman FOSS is more likely to be secure on average, but that doesn't mean that there aren't plenty of insecure things. Also it's not just about checking the source but also about the developer knowing that their code might be checked in future while writing it. That's an important psychological deterrent against backdoors, antifeatures and other malware getting into FOSS.
@clacke @bes Riot seems to eat battery power, although I was subscribed to the main Matrix channel which is high traffic. It might be a similar problem to Antox though in that perhaps it indefinitely keeps the connection open, preventing the device from going into sleep mode.
