XP was trash, people thought so at the time, even more so before SP2, so I don't know why anyone would willingly use it. Really the only reason it was ever popular was because XP was the only usable OS out there for like 6 years. Of course MS still has the rights to it, why would ending support change that? If you really want a free OS capable of everything XP is (plus it actually loving works more often), use WINE on Linux.
