I don't believe one can make a business case for Sony making more money by granting TM an exclusive. Sony's primary interest is in moving consoles. The best way to move consoles is to provide legacy support to ease the transition from one generation to the next. An exclusivity arrangement with TM is in TM's best interest, not Sony's, because you're throwing up a huge barrier to entry into next-gen by giving that arrangement. I believe TM's revenue is in the $20million range so paying an exclusivity fee to Sony would amount to only a couple million at best, which Sony would likely lose dozens of times over by not allowing Logitech and Fanatec owners an easy transition to the next console. The most likely explaination is that Sony came up with the security chip idea and assumed that wheel makers would just play along and create new hardware to work with the system. Problem is that Logitech was out of the console wheel market and didn't care at first and the only one that could afford at the time to meet the requirements and jump through the hoops was the biggest of the other two. TM and Fanatec are relatively tiny enterprises compared to Logitech and Fanatec in particular is quite small. They probably struggled with resources and in deciding whether to make an all new wheel, or go the route they did go. Pure speculation of course, but it's an explaination that fits all the available facts and needs no conspiracy theories to make it work.
