Accepting that we should instead support technologies that place those very same populations at risk is coming from a place of privilege for the reasons I mentioned previously: you live somewhere with relatively peaceful/democratic governance, usually have at least some ISP choice, and are likely not otherwise under the thumb of an oppressive regime at some level of another - so when your browser makes a TLS1.0 connection, you probably don't even think about it, much less worry about it, because you don't have to. The populations we're discussing here, on the other hand, all too often do.
What it comes down to is a question of whether we want to solve what we know today is a real problem or let it fester until abuse reaches an untenable level in some big, news-headline-making way. One way we can combat this specific issue is to make open technologies accessible. But that requires major investment on our side of the world, and prior attempts to do so (Ubuntu's open source phone OS for example) have largely been commercial flops.
