This. Linkedin is garbage, yet I still use it because there are no competitors. This is what happens in a monoculture.
Do you really want a “competitor” to linkedin? Do you really want to have to make and manage accounts on multiple sites because you need a job and you don’t know which a company uses?
Isn’t it better to have a single place you check when you need a job because everyone else is also there?

As someone who doesn't, and never has, had a linkedin. What would a "competitor" look like? There's plenty of job boards. What are you using linkedin for?
