Actually WWE does mind, and TNA still insists his name is Sean Waltman...and it isn't wrong for the announcers to say he former wrestled under the name X-Pac...what you are probably thinking is that Raven called him X-Pac...which was done in a promo and for some reason you're allowed to make references to other promotions copy rights in promos. But yeah WWE still owns X-Pac and Syxx...though not Syxx-Pac.
