Your incorrect claims won't become better by personal attacks against me.

What would TLS protect against when sending an email to a public
mailing list?

The contents (including all headers) is anyway public, and if either
of us was worried about someone modifying the contents of the email
he would add a signature.

Against someone like the NSA the improvement is pretty marginal,
and I doubt it would increase the work they have to do much.

Encrypting the contents doesn't help much when you can deduce the 
contents from the timing and amount of the transfers.

Your claims that using https for that purpose would give any kind of 
protections against actors like the NSA are just snake oil.

Pretty dangerous snake oil, if someone ends up believing what you wrote  
instead of using a proper solution like apt-transport-tor.

Debian is an Open Source project, and the only way you can improve 
anything is by doing work yourself - if all you are doing is producing 
hot air, you will achieve nothing.

People have already pointed out several areas where work needs to be 
done for using https by default, and if this is important for you there 
is for example nothing stopping you from starting to work right now on 
improving the https transport in apt.

Or you could prove that it is actually not that important for you by 
doing no development work for that.

Noone is arguing that switching to https would be a bad thing,
but whether or not it will happen depends solely on whether or
not people like you will do the work to make it happen.
