I am looking for an alternative for email in the first place.
When I got my first computer time ago a neighbour and friend installed all I needed and that's why I had my account with yahoo. Those were modem-times and I didn't really need an email but a computer to write for my work.
Now, after migrating to flickr (because I already was at yahoo is one reason), I get the message every time I enter that both yahoo and flickr will be owned be oath. I am the only one to blame that I never before read the contract, but now that I did, I don't want to be tracked for any reason and the least of it is the commercial advertising.
My pc settings protect me from most of it.
But if there would be a alternative, far away from multinationals, far away from government abiding (but no tax paying) giants of modern communication industries, then 'll move.
I don't need encryption, nor is it a matter of 'nothing to hide'. It's about privacy and independence.
As I still will need some older posts I cannot quit yahoo; and in the moment I'll stay with flickr, too. But I'll get a new email-provider as soon as I can.
I'm fully aware that there will be tracking each and every time I use a 'service' that is provided by one of the usual companies (even without knowing that I am using theirs) - but I'm not a communication professional, there will be many incongruities I'm not aware of.
