Except for one small detail. You *can't* implement your idea. I can implement mine.
Uh, yes, I think buiding this would require closed source tools... drills, screwdrivers, etc. I've never been supplied with plans for making *any* of those devices when I bought them.
Yes, this is the way they manage their market. But your analogy really isn't very realistic. FPGAs of the last 10 years have had a lot in them other than LUTs and FFs. I think they are reaching a critical point where over the next five or certainly 10 years they won't be able to sell the same sort of stuff the same ways because so few users will need10,000,000 LUTs on a single chip. Instead the logic will be swimming upstream into more complex blocks like small CPUs and they will be programmed by software rather than a small LUT. This is what the GA144 is like and I think the future will be ~similar~ to this device. Maybe then they can become a commodity device.
There won't be any "disruption" because there are too many patents. A new comer is severely constrained to rather old technology in many ways. Most large companies are patent trolls just like the ones everyone calls patent trolls... even the president.
Don't hold out too long, you may be dead...
