So, we have the usual reaction to something like this: Nintendo fans saying it's not an issue and Sony fans declaring it's a huge problem and the console is going to fail, jumping with joy. Stuff like this always reminds me why I left this site for a few years.
OT: Let's see how big of a problem this is. My Wii U gamepad has the same "problem" but that never stopped me from playing. The Wiimote's pointer didn't work either when you covered it and the Wiimote+ had to be re-calibrated regularly. As long as you don't cover the joy-con with your hand it should be fine. Didn't stop the Wii at least. But we'll see.
