[Starlink] Starlink Digest, Vol 12, Issue 6

Fri Mar 4 02:00:03 EST 2022

IMHO unless we are addressing actual weapons, we are in murky waters. Take toilet paper. It is an element of Molotov cocktails, does it become classified as a weapon? Or in fact, anything that can aid one of the sides in their fight, including food and medical supplies.

Our WISP in Kenya gets asked, very often, “why do you provide internet in slums, don’t they need like, food, clean water, healtcare, before internet?”.

The answer to that is two-pronged. First, we are good at “doing internet”, in a way cost-effective enough that our business actually employs hundreds of Kenyans, many from these slums, and provides unlimited broadband internet to underprivileged communities at affordable prices. We don’t know how to “do" clean water or healthcare, so we try to make an impact with what we know.

Secondly, the Human Rights Council of the UN produced, in 2011, a report, which stated:

"The Special Rapporteur underscores the unique and transformative nature of the Internet not only to enable individuals to exercise their right to freedom of opinion and expression, but also a range of other human rights, and to promote the progress of society as a whole”.

Many news outlets picked on this to conclude “The UN declares internet a basic human right” - which is not what the report says (full text here: https://www2.ohchr.org/english/bodies/hrcouncil/docs/17session/A.HRC.17.27_en.pdf). What it does say is it can enable the right to freedom of opinion and expression, something which Russia is trying to shut down, both in Ukraine and in Russia itself, applying sanctions to those who disseminate “non-official” information.

Thus, my personal view is that a few Starlink terminals that can restore connectivity to areas where it has been limited, have benefits that outweigh the possibility that they get used for military comms or such.

Best,

Mike

I'd personally grieve if anyone came to harm as a result of any insight I'd shared here, and I don't care whether that would be a Russian soldier or a Ukrainian freedom fighter, or heaven forbid a civilian not involved in the hostilities. I've already had an indirect approach from a party in the conflict this week to provide resources for cyber-warriors, and have politely declined and informed our university's chief information security officer, whose response to me was that he would have been a lot less polite than me.
> A significant part of the tensions you currently see explode in Ukraine have festered for decades and are rooted in Russia's gas exports to Western Europe. That gas has flowed for many decades, a big part of it through the territory of today's Ukraine. The pipelines go back to Soviet days when Ukraine was part of the USSR. Germany, as Russia's main gas customer, always found their Russian business partners to be reliable and faithful to contracts signed (my father was a commercial lawyer in the city of Essen, and dealt a lot with Ruhrgas there, then Germany's biggest gas company and the USSR's / Russia's biggest customer in Germany, and knows the former CEO). When the USSR fell apart, Russia suddenly found itself with another transit country along its pipeline. Ukraine insisted on being supplied at rates they would nominate. Russia was faced with a choice between supplying Ukraine for cheap or losing its ability to supply Western Europe. That's why they wanted the Nord Stream 2 pipeline so badly. After years of multi-party negotiations with the US trying to talk Germany out of saying yes to the pipeline, the Germans were left with the impression that US insistence was in no small parts motivated by them wanting to sell US-produced LPG to Europe.
> None of that is an excuse for a brutal invasion, of course, but maybe a reminder that life is sometimes a bit more complex than is suitable for a simple good-bad scheme.
> I laud Starlink and other initiatives for adding options to preserve connectivity for people in Ukraine, however small these options will be in scale, and hope that the good that will come out of the ability to support innocent civilians and shine light into dark corners will outweigh any use for the pursuit of hostilities and any risks to those using it.
