I am fully agreed with your points.
Two weeks ago I got a chance to visit a famous optics store in Europe to buy a pair of 10x42 NL Pure. They strongly recommended me not to buy Swarovski products and go for a Nocivid. Their point was the same problem discussed in this thread as well as following thread->
EL 10x42 casing deterioration. ; the armor of recently manufacturing Swarovs is degrading particularly when use in tropical countries. They said 15 out of 50 NL Pure bins sold have been returned due to a problem with either rubber armoring or the focus knob. Moreover, one of my friends changed his armor in SLC 10x56 less than two years ago and today I saw a recent photo of him with his bins. Check the current condition of it in the pic attached.
The point here is a lot of people are confused with the word sustainability without considering a life cycle assessment. As you mentioned, sending a pair of binoculars a few times to change the armoring costs petroleum, manpower, and new materials that increase the ecological footprint. So, I can't understand why Swarovski still sticks with their new material even with a lot of complaints about it.
