There’s some older article I found: https://www.reuters.com/article/world/uk-dutch-spy-agencies-curb-intel-flow-to-austria-over-russia-ties-mp-idUSKCN1RL2CL/
And if I didn’t dream it up (can’t find exact source, sorry) Austria whilst not in NATO was part of NATO intelligence sharing network back in 2022, but they were booted at some point due to leaking info to Russia.
The fact that Russian delegation in Istanbul among other things demanded that “both sides will refrain from suing each other in court” just tells that they know really good how fucked they’d be in Hague.
