Klaus, I think it's time to step up and maybe allocate your time for a greater project. Associate with other websites (lensrentals, dpreview, imaging-resource, german sites, german, petapixel, ..., ...) and try to establish a HUGE lobbying campaign. I think you would, at the very least, release frustration. Use social networks,
Photographic lenses are extremely expensive object. We tend to think "it's normal" and we get used to their price tag but I think we lost our critical thinking. Paying 400€ for a simple prime lens for aps-c to find out it's dodgy from day 0 is inacceptable, regardeless of its intended use (large printing or not). And don't get me started on the bonky 17-55 and the likes at 1000€ a pop. Europeans have perhaps stopped "mentally converting" to their old currency but when you do, it's sure is scary expensive. I agree that there must be "limited pixel peeping" involved too, and that we should mostly look at visible issues.
You could possibly even look for industry support (albeit challenging the venture itself). We need to wait for more feedback but what if Sigma's efforts were actually successful and measurable and that they could pressure others into QC ?
Sigma got it well lined it seems, new materials, new optics (hoya), new QC, still competitive on the price. What about others?
I feel like you don't really want to do this anymore :-)

Honestly, this industry is a joke. The next time I will test a coke bottle - it has a proven design for more than a century. Their bottles are certainly perfectly centered by now.
