French MOD have deployed matrix locally for their private usage. not sure they want to use a software that the mossad can directly tap into

I wouldn’t put any stock into that as a metric of if it’s safe or not, since France was happy to buy a contract for Pegasus, another Israeli surveillance software adopted widely by EU governments such as France, Germany, and Spain.

EU governments were also happy to adopt Microsoft products despite the security implications, and even way back in the 80’s used Promis, which had a known US/Israeli backdoor in it (there’s a really great documentary about Promis on netflix, surprisingly, though I’d recommend sailing to watch it, yarr).
