For some time I thought I was the only one with issues on LinkedIn. I'm happy to see I was wrong.
My fundamental issue with it is that I believe it takes more from the society than what it gives back, it's extractive. On a world where inequality is rising and unemployment is hitting records on multiple countries, LinkedIn keeps its approach of having to pay $29 to see more things and get advantages. If you're based in countries where $29 is too much, too bad for you.
Its purpose is to make money with my job search, not with the fact that I found a job.
