Tried to watch the whole video but dude just comes off as another one of those fake outrage idiots making a huge deal out of nothing.
You don't need to buy the heatsinks. They come already installed on the SSD.
It also isn't very complicated at all to install one. Sony releases a video showing how to do it when the PS5 released. Just pop the side panel, open the expansion port, put the SSD I'm, close it all up and you're good to go. Much simpler than installing on a PC, and comparing the two is idiotic.
