It's definitely something I have a serious concern over. I also have serious concerns about certain types of personal account being required for employment. I have personal microsoft, github and google accounts that I don't want, but had to create because I had to access msdn/github/google cloud console or I would not be employable. None of them provide a mechanism where my employer can open an account under the name of the company (so I bear no liability), bestow it upon me as a work asset, and then revoke it when I leave. AWS provides this in the form of access keys which are god damn great, but they're an exception.

At some point, we will have to start auditing and regulating the responsibility that companies owe to society once they come to dominate a field. There's a scary chance that LinkedIn might capture almost all the professional job market. Once that happens, we /need/ to be able to audit them to ensure they are fully complying with witness protection requirements, and to make sure their algorithms don't contain race biases.

Look forward to that one being the hot topic of 2025's legal circles.
