Dont know if this test in a good representation of the two AI, but in this case it seems pretty promising, the only thing missing is a high parameters model
There was others open models but they were very below the "fake" open source models like Gemma or Llama, but Instella is almost to the same level, great improvement
Basically if you don't want Tor reliance it's surely that you are not that privacy focused in your use case :)? So there is not really a point of using live/disposable os..
But if you still want to, use any Linux live/testing USB installer
Linux mint, fedora and more provide it ;-)
In any case a service that implement E2EE is always more secure than plain data transit
Even with a backdoor it's a bit more secure than regular service
But you should be angry against the UK law cause of the probable future consequences that will impose even further surveillance for other services
But people that defend it are probably mainly Apple fans. Apple is "against" to maintain a "privacy" friendly company against google and meta, but it's bullshit
Mistral --> pseudo-open-source
Linux --> not relates to Europe (but amazing choice)
Vivaldi --> only source available
