Just listening to you on the Europe situation and the backdoors they want on the chat apps. On Android you can side download as u mentioned, weird thing for them is that in Europe Apple will be forced too to allow side downloads too if I recall well. Which means that to enforce it they may have to use mandatory proxies or something like that. For travelling it will be a pain!!
