You are taking this personally. Just because I see the images and I read the reviews on the image quality and the build quality, and I say that I wouldn't buy it because of those issues, you are conflating that into my making a judgment call on your personal choices. I'm not. I'm making a judgement call on the performance and the build of the lens, as are others here and in other places. It will work for some, but not for others. The flip side of that coin is that if you want this and other low cost lens alternative threads to be taken seriously, you shouldn't belittle the choices of others or the lenses they choose.
For me, Fujinon has been and still are some of the finest lenses ever made. The same goes with many Pentax optics. The older SMC Takumars are world renowned for their performance, every bit as good as Leica or Zeiss. Konica Hexanon lenses are stunning and folks are now paying attention to that, driving the prices up. But I still own a Leica lens, and most of what I use are Nikon lenses. I'm not out bashing other manufacturers because I was hurt that I paid too much for their lens. I've felt let down by the reliability of some cameras but I've never vocally complained about a lens I wanted and purchased then didn't like. I loved the original cosina Voigtlander 35mm f/1.7 but it fell apart, in spite of giving great images. Eventually it had to go.
When people purchase Leica, et al. they are not just purchasing superlative optical performance (which is overpriced, in 35mm, I agree), they are purchasing haptics, ergonomics, compatibility, extraordinary build quality, and buying into a legacy of photography that goes back to the very beginning of miniature format still imaging. If you don't like that, that's ok, but don't belittle the photographer or their choice of lens because of your personal feelings.
