Recent article I read from someone who works on Android: https://jakewharton.com/removing-google-as-a-single-point-of...

A few years ago I was considering applying for a job at FB. The very first stage was linking your FB account. No thanks.

Pretty sure FB wont even hire you unless you are a fanboy to begin with so it's a weak barometer.

Well wouldn’t fan boys who stop using fb after they get an inside peak be a good barometer?

Googler here. Yes, there are many google employees that do not use Google products for personal use. Firefox, for instance, can be used on work machines.

I use Google's products because I have to. The alternative is spending huge chunks of my time to "work around" Google. Same goes for Facebook, except there is no work-around.

This does not mean I support either company, it just means they have manipulated culture to ensure they are the only choice.

Not sure if it's still the case but it used to be that employees used their FB accounts as logins to work systems.

Not any more. When I started three years ago, it was a mix of people doing things the old way and people with split accounts. Less than a year later, it went to all split accounts. Also, FWIW, the number of my coworkers who actively use "public Facebook" seems very small.
