Anyone can download them to look for anything. Switching to a specific format which really is not common at all on older distros nor on any system looks a bit like proprietary encoding eventhough it's not the case. But it's a way to tell people that if they want the sources in clear text form, they first have to find a tool capable of decompressing them. Gzip is well defined as a standard, it's even described in an RFC and is present on almost any system (unix or not) now. Any student who wants to take a look at the kernel will have access to gunzip, even from an old Solaris 8 workstation or a Windows XP desktop PC. XZ if far from being there, and the student will not necessarily be able to install it. And Peter raised some valid points about the hardware requirements to run such tools ; I'm not sure the guys running Linux on their old Sparc-2 would like XZ only a lot.
