Fastmail is not available to everyone on the world.  From the last 24h of logs we have about 96% TLS, 4% without TLS.  Plenty of which is spam of course, but I did enough of a random sampling to see that not all is.  And plenty of the TLS email is spam too.

Sure it's a small percentage, but it's still a chunk of customers who would not see emails they want to receive if we switched it off.

I note that postoffices also don't require postcards be sent in opaque titanium shipping envelopes, even though anyone at the post office can read the scribbled "The weather is here, wish you were gorgeous" on the back.
