Honestly, it looks as if some jokers
just slapped all the anti-user things they could think of, advertised themselves with bullshit like the Metadata Mitigator™ - for which of course you have to pay - and went around
their merry way while raking in the cash. This might be worse than Gmail, which is more honest in regards to their (lack of) privacy and provides all its features for free.
