i might be wrong but unless they are bootleging I think they have to go that way. Now, they have bootleg routers so one could believe there are bootleg wireless ones too. Not worth the headache for me support. 60 bucks a year to lease the stuff. But to each their own.
60 bucks /year is not a lot of money, but if you keep your ISP for two or > years , you'll kick yourself for not purchasing the equipment. I have a router that I have been using for 4 years....I would hate it if I had leased it...
