Because, as the ssh_config(5) man page states, X-forwarding is no longer
enabled by default.  You must either specify "-X" or "-Y" on the command
line or put a "ForwardX11 yes" line in either the system-wide
"/etc/ssh/ssh_config" or your local "~/.ssh/ssh_config" file to make it
work like it used to.  I DON'T recommend the system-wide enabling of
it for a public-use machine.
