I think Signal shot themselves squarely in the dick by removing SMS functionality.
Previously, you could use Signal as the primary SMS/messenger app. Any conversations with other Signal clients secure. Conversations in SMS/MMS? Marked as not-secure.
But, out of some purity concerns, SMS functionality was removed and the dev team focused on adding useless shit like “stickers” and then the pin-code harassment.
Signal adoption plummeted as intended (?)
All this tells us is that Russia has literally zero anti-aircraft/intercept capability — even for national-level strategic sites.
They keep getting their turds pushed in by radio-controlled light civil aircraft pottering in thousands of km at highway-traffic speeds.
Pitiful.
