I agree that is a weak example. I think the others are strong, and it is increasingly true outside tech too - lots of brands are just rebadges from a few actual manufacturers.

It is still possible to find a job without LinkedIn, but more and more companies are requiring a LinkedIn account in the application. So the future looks bleak in this area too.

Either one of us is in a bubble (or likely both), because I never heard of any company requiring a LinkedIn account for applications. I would consider this as a major red flag even.

Where I live almost nobody uses LinkedIn. Many of our clients that do use it, have either been phasing it out or are simply not engaged with it in any way.
