Worked on a project using them a couple years ago and it was a complete shit show. Stuff like atrocious documentation, spaghetti code demo projects and very difficult to reach support. We surmised that their auto core builder thing was actually probably a few people manually configuring and firing off build jobs rather than any truly automated/turnkey process. They also lacked a lot of peripherals/interfaces that you'd expect or, more accurately, need for any product leveraging the performance the cores could theoretically provide.
Long story short, this isn't super surprising given that it basically killed our product.
