Meaning less than 15% of the idiots complaining about a removed feature they never used were full of crap because their console indeed never actually supported this feature.
Nice statistic. It's a shame you chose one completely out of context with the issue at hand. Cherry picking statistics out of context hurts your argument more than it helps it.
At the specific point in time Sony released the update that removed support for Other OS, the percentage of PS3s on the market that did have that functionality was much higher than 15% so your point is invalid. Even if your statistic was accurate, what would it matter? If even 1% of the PS3 owners bought a PS3 for the advertised Other OS functionality, the complaint about something they paid for being removed after the sale is still valid.
Beyond that, they didn't actually remove it from the ps3s that shipped with that support, the USERS removed it when they upgraded the firmware, something Sony gave advanced warning about. No excuses.
Again, you're cherry picking facts and using them out of context. Sure, the users upgraded their firmware but they only did so because Sony intentionally made a multiple other features on the PS3 stop working if they did not update to the latest firmware. In other words, Sony forced PS3 owners to choose which of the original, advertised functionality they would give up.
Unless you are the US army building a cluster, you had no use for this feature at all. But.... many butthurt morons were butthurt because they thought, incorrectly, that this "other os" feature allowed for piracy.
Wait, let me get this straight. You are reading and posting on a site known for it's Linux advocacy/fanaticism and you essentially just said you don't see any other uses for the ability to run Linux on hardware that was purpose built for media playback other than military cluster computing and game piracy? Either you are being intentionally obtuse with the intention of trolling or you are incredibly unimaginative and just plain ignorant of the potential the PS3 had as a HTPC running Linux.
Car analogy time. What Sony did to the orignal PS3s would be like you buying a car specifically because the manufacturer advertised electronically selectable driving modes (i.e. normal, sport, track, etc.) as a feature on it. 6 months later, you take the car in for the manufacturer's recommended maintenance. The service department tells you that the manufacturer doesn't like how owners have been driving their cars in sport and track modes, so they have to install an update to the vehicle's control module that disables the selectable driving modes. If you don't install that update, your radio, power windows and locks, and sunroof will stop working after a certain date. You still have a drivable car but it is most definitely not the same car you originally purchased from a functionality standpoint, regardless of which option you chose. I suspect you would be fairly unhappy with the manufacturer at that point.
