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.

A lot of the stories on that site are from corporate, not the warehouses.

Also I know a lot of Googlers as well (hard not to living in Mountain View), and they work roughly 40 hour weeks in general. It is night and day between Amazon and Google based on the stories that are coming out from current & former employees. I've heard issues about Apple as well, but nothing on the level of the stories coming out of Amazon.
