It all started with the warehouse worker complaints, which were general complaints that any warehouse worker will have and not really egregious comparatively. This fed into a media narrative and causes sites like that to pop up.
When startups ask a lot of their employees its showered in praise. When Elon Musk demands 100 work weeks, people are in awe of how great he is. When Nest does the same people squint because Google bought them.
I know a lot of Googlers, most put in ~50-60 hour weeks but get free lunch so its ok I guess? Same with Apple.
