Not really.  You choose some.  There are other players that will
manipulate paths to save themselves money or bandwidth too, so it's all
a bit like a real-time strategy game.

Nobody has talked about taking away rsync which you can use to run your
own mirror.  debmirror and others also support mirroring over HTTP so
you'll always be able to able to mirror if you want to.  Whether that's
possible has little or no bearing on if ftp.$cc.d.o is the default apt
download location or if it's some other CDN-ed name.  (Which isn't what
we're talking about initially, but a point we might eventually get to,
some years down the line.)
