I don't know if all FAANG companies are the same, but your description of the job does not match my FAANG experience at all.

It was dehumanizing in its own way because you are such a small cog in a large machine, but nobody worked long hours, nobody was forced to be available all the time, nobody really needed to sacrifice for the company (because everybody was such a small cog) and even the lowest performers I worked with could basically not do anything to get fired. Many people there were also "lifers" because the job was so easy.

Most people left due to having ambitions for more impact, not due to being burnt out.
