Thanks for your feedback, but what you are saying is not at all representative of the feedback I received after thousands of back and forth emails over the years. Thanks to the updated manual and firmware process, those who have never used a Model F before tell me they were able to easily set everything up and it works fine.

Having to adjust more springs because there are more possible keys that need to be set up on the larger layout keyboards does not mean that QC has gotten worse over time. That's just because there are more keys on the keyboard that it's more likely that at least one or more springs need adjustment.

The most common setup step is just adjusting springs and reinstalling a key if it doesn't click the first time you install it.

The warranty includes replacements for parts because the user replaces the parts like keycaps, springs etc. if they are broken. I just mail the parts for free as part of the warranty. My post that you replied to notes that a full mail-in warranty service would not be sustainable, so there is no real way I can offer a labor service. The manual emphasizes that I can't offer free labor to set up or maintain each keyboard; following the manual will give everyone a 100% working keyboard.

This is not a kit for tinkerers; it's for folks who have a buy it for life mentality and are not afraid to use tweezers and a key puller to reseat something over the coming decades. If you follow the manual, your keyboard will be working 100%, but you do have to adjust the springs and keys and go through the setup instructions. I explained why it's not feasible to offer increased service.
