I'm not a massive fan of Tyler Nelson, but he seems to be arguing that Lattice had him in to do some consulting for the product, and that they used his measurements. If that were me and I read the Lattice guff about "100s of hours research" and all of the hyperbolic marketing around it I'd probably be pissed (maybe not enough to
record myself playing Master of Puppets and stick it on social media with a caption about "blowing off some steam", but we're all different).
It's fun that rather than addressing any of this Lattice are getting into the Evil MegaCorp schtick by deleting comments on their Instagram posts and YouTube
advertorial completely coincidentally timed 'how to do finger lifts' video with lots of close-ups of their new product. It seems a weird approach given it'd be a lot easier to just say 'yeah, people have been doing this for ages', 'no, we didn't steal your idea/data'...
