Why has Ubuntu moved the default mount points?

Why has Ubuntu moved the default mount points?

Why has Ubuntu and many other Linux distributions moved the default mount
points from /media to /media/$HOME
Example I plug in a USB drive and it's name is EXT4-250GB-USB it used to
show up in /media/EXT4-250GB-USB but now it shows up in
/media/z/EXT4-250GB-USB
Why is this and what's the reason behind it?
