That's apples and oranges though. Tor is out of control of the US military as this point (+/- your tinfoil hat level), whereas Google Translate was created and is owned solely by Google. I'm not saying GP is fully correct but context is important.

I personally think using transformers for, well, transforming input into another language is going to be a great approach once hardware catches up for local offline use at a reasonable speed and hallucinations are minimized.
