Jenoptik owns Sinar, Jenoptik hired F&H to develop the Hy6.....Jenoptik (and perhaps Leaf) have full control over whose backs will mount on the Hy6s, and they don't want Phase backs on the Hy6s because they want to put Phase out of business
You have a vivid imagination. There has not been one shred of evidence offered by you that supports these rather presumtious statements. The BJP article ONLY says that Rollei, Leaf and Sinar will sell branded versions of the F&H Hy6. The F&H documentation I've seen suggests they own the Hy6 design, not Jenoptik. You go on and on about how Jenoptic owns the design because they put 4 million euros into it. 4 milliion euros is a pittance, and I doubt it's anywhere near enough to buy the design outright. 4 million euros, assuming they really put in 4 million euros at all, is at best only the licensing fee to allow Jenoptik to sell a Sinar-branded version of the Hy6. Nothing more.
Bottom line - you make very presumptious statements as if they were facts, without offering a shred of proof. The BJP article doesn't prove anything, and in fact suggests something much narrower than your assertions. At this point, the people who do know the facts aren't talking.
Just because you believe something is true doesn't make it true. When you have proof that Jenoptik paid 4 million euros to F&H, and when you have proof that Jenoptik owns the Hy6 design, and when you have proof that Jenoptic somehow has veto power over whether Phase backs can appear on the Hy6, and when you have proof that Phase backs won't appear on a Hy6, then post it. But until then, you're just engaged in speculation like the rest of us are.
