What kind of attitude is that? Or to answer: Because they want to sell cameras? This is not some obscure lens we are talking about.
If a 3rd party lens does not work properly with the body, but Pentax brand lenses do, why is that Pentax's fault? They need to sell glass too, bodies are not their big money maker, glass is. They probably aren't purposely sabotaging the Tamron glass, but why should they modify their body to work with glass they did not make?
Tamron does not license the use the K mount from Pentax, I don't believe they have licenses from any of the manufacturers, they reverse engineered the system to make them work. Just like Metz and Sigma reverse engineered the flash system, almost every updated body require a firmware update to the Metz and Sigma flashes to make them work properly again, yet an old Pentax AF360 that was bought years ago for a *istDL will work fine on a K-30 with no update.
