No, I completely understand the point. He speculates that if the camera uses the same component that it might have the same problem. My response was to wait and see. In other words, if you are concerned about product weakness, it is best to not be an early adopter and only buy time-proven models*. One might also speculate that the K-70 uses mostly components from the K-3II including the more robust shutter/mirror/aperture controller from that camera with frame rate downgraded to 6 fps for marketing purposes. There is no evidence to support either assertion, but that is my point. If I were mocking, I would have suggested that we might also speculate that the K-70 is actually made by Monsanto using lubricating oils derived from GMOs...but I did not do that.
As for the assertion that I refuse to admit that there is an issue with the K-30/K50 aperture/mirror controller, you are badly mistaken. I was one of the first members of this site who assisted the initial wave of K-30 users who had this problem (2013), have closely monitored the issue since, and have been quick to suggest this particular failure when people submit K-30/K-50 troubleshooting requests. I also have personal experience with the failure with a close friend's K-50 (1 year post purchase with low shutter count) and have been through the warranty repair process here in the U.S.
I have a high degree of sympathy for those who purchased their cameras new and now find them out of warranty without having gotten much value from their investment. If they are within two months of warranty expiration, I usually suggest they contact Pentax to see if they will still fix their cameras. For those who believe that this failure is a universal problem afflicted all entry-level/consumer model Pentax cameras made since 2013, I suggest exploring whatever legal remedies might be available in your country of purchase.

* In Pentaxland, the best examples would be the K20D or K-7, both of which have virtually spotless defect histories and both of which have the same aperture control block design as the K-30/K-50.
