UA UAV engineer here with a few cents.

1. Serhii Flash (a very authoritative source on UAV connectivity) publicly debunked the whole "note from friendly engineers" thing as well as the idea that RU UAVs are able to use mobile connectivity in Ukraine en masse. There is no hard source for the note either.

2. Telegram is just hands down the most convenient messaging up there is from the user experience, chances are if Russians use Telegram to get drone telemetry, this would only be for the reason to keep all tabs in the same window. Same as anyone using Telegram bots a services up to Ukrainian government ones (e.g. traffic fine monitoring) because it's just a convenient thing to do.

3. There is nothing special to Telegram in means of creating a secure two way link so long as you have connectivity in first place. I literally did just that on our system for debugging with just an SSH tunnel. It's solvable by any half competent IT person so Telegram in itself would only provide some quality of life, but not a technological edge. The fact that Telegram is hard to filter is only relevant in the context of mass medias and regular users, not when you are rolling a telemetry system for devices you are in full control of.

4. Telegram's encryption (MProto) is home-grown and have been subject of many theoretical attacks and criticism. In general it's a bad idea to roll out your own crypto, so the best way to describe Telegram's security is "we don't know" and that would include risks for Russian operators too. That argument is absolutely not in favor of Telegram usage for the military and for Russians it'd be a sign of complacency above all.

5. The issue of mobile connectivity in itself is being worked by Ukraine in a systematic manner. As with anything it's a back and forth battle, but there is no evidence to suggest that Russian UAVs can efficiently use Ukraine's networks. It is plausible of course, but The Economist just went all out with spreading rumors which is hardly helpful for anyone.

tl;dr if Shaheds use mobile connectivity over Ukraine, that happens in a very limited capacity and has absolutely nothing to do with Telegram and its capabilities whatsoever.

Sigh... If only we all had a universally used "standard" proper messenger (for daily private communications, not "social media presences"). If only it was so easy to make everyone I know use only one of these. But no - Microsoft had to kill off Skype and I'm stuck using a wild jumble of telegrams, vibers and facebook messengers - none of which I trust or even like, but still have to use to communicate with literally 1-2 persons in each one.

Well, at least I'm not in the trenches.
