Swaro looks like a small company .... less than 1000 employees in Optics, so their Engineering/Technical team are likely small. This Engineering team will have to cover research, new product design & dev, manufacturing support and in-service support (assisting the Quality department for warranty type issues like we are discussing).Yes you are correct
In this case of sticky rubber I'm sure they can't afford to have many binoculars go sticky over five years, and in the XXIst century this problem is not unfixable (hey, most leatherette never fails). So remains the possibility they have low incident count and then chances are you won't have twice the same issue.
I've been working with a number of companies who have strong focus on quality and put a lot of effort and energy to understand and fix quality issues. Companies like Swaro who are handling the warranty repairs in-house are in an excellent position to do so and I would expect them to handle the matter seriously. But who knows...

With the ongoing armour issues affecting many bins, I would not be surprised if this low incidence issue on a low volume model is far down the pareto list of priorities!
