This issue has been interesting for me to read about.
Quickly summarizing what I've been able to glean from the web:
1. Venus announced their lens in January 2015 (
ref). Nobody disagreed with their claim to be the first lens with a range of infinity to 2:1.
2. The Oshiro version became available in or before February 2016 (
ref).
3. The Oshiro website (
HERE) makes claims that appear identical to Venus.
4. Oshiro advertisements appearing at Amazon show images that appear identical to Venus's, including what looks like a Laowa logo -- or something very close to it -- on the front of the lens. Compare these images:
5. Venus is a Chinese company; The Oshiro website (
HERE) says that
"Our production and assembly factory is located in China."

I contacted Venus Optics about the Bresser lens. This was their reply:
Please note that the Bresser 60mm Lens is a complete COPY of our Laowa lenses with extremely poor quality. We are now working with legal team to take them down. All our lenses design are protected by patent.
The main difference is the focusing ring and front window opening. The focusing ring of our Laowa product is metallic while the FAKE one is rubber. The shape of the window opening is also different.
Attached please find the REAL/FAKE comparison image for your perusal. Please excuse us that it is in Chinese at this moment. (LEFT: Laowa, RIGHT: fake)

I won't be getting the Bresser myself.
If I had to bet, I'd go for a combination of Enrico's explanation plus blatant ripoff of images and device description.
That said, the situation is murky enough that I wouldn't think ill about any purchaser who selected the cheaper option.

It's just a guess, but I expect they'd take the lead from my own reaction. There's an example of that at
http://www.photomacrography.net/forum/v ... 151#120151 and in the surrounding thread.
But of course for me, the issue is never "new stacking software" but rather unauthorized exact or nearly exact copies, complete with my copyright notice, that are packaged with stolen licenses. Once you get one of the packages in hand, it's pretty clear what's going on. For me, I think those packages don't really represent lost income, on the theory that (a) anybody who actually uses one probably would never buy a license anyway, and (b) people who visit those sites tend to be punished by malware, so the problem is sort of self-limiting. (That doesn't mean it's small, however. The results from a Google search I just now did on
"Zerene Stacker crack" started off by reporting
"About 93,700 results".)
For Venus, the copies would be much more of a problem, because the copies
look legit and actually do work well. So for them, it definitely would be a matter of lost income.
