Of course, yes there many parts to that equation for sure. However, the outcome is that Ultimaker printers are becoming unusable in terms of productivity. In particular if compared to new brands and at that price point.
And, I have been trying to fix the issues for many years now without success. Bug fixing was ok in the early days of Ultimaker...now, not so much. If other machines just work out of the box without issues, the outcome is clear.
