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.
Thank you Austria, but we still remember how you leaked NATO intelligence to Russia, so get bent.
Well, they've been going for a while now. I'm Ukrainian-speaking in daily life (and has been for my whole life), but I'm fairly fluent in Russian simply because it was everywhere - TV, Internet, music, and foreign companies didn't even bother with Ukrainian-speaking demographics when shipping their products (i mean, for example, markings on appliances and such) or releasing software with Ukrainian language until we had laws that demanded that, they just did Russian, because "they'll understand it anyway".
While I remained Ukrainian-speaking, some people bought the idea of Russian culture being trendy and modern in contrast to Ukrainian being portrayed as rural and simpleton. And that was just "long war" , before it even went into open hostility - there were years, decades, even centuries of such conditioning, but also periodic revivals of Ukrainian culture.
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.
