Let's analyze your sentence carefully:
" People from different countries and backgrounds are not identical in terms of vision, sensitivity, and preference"
Maybe some nations prefer sloppy tracking while others like blur images. Who knows ?
"It's not our plan to hide the prototype in the lab until the product perfectly done."
Really ? Then where is the pictures and videos with your progress between november and now ? The community begged almost daily for benchmarks and info about your progress. And yet you came out with nothing. Until now.
I dont' want to be a hater. I just say that from now on I need to change the way we interact. I demand more transparency about what you actually do not only declarations which cant be proved.
And I didnt use the word "we" too much here (despite I should). Everyone is on his own, it seems to me here.
