I deleted my LinkedIn and all other Big Tech accounts the day BigTech deplatformed Parler and Trump. Turns out I don't need them at all, anywhere. . . other than a $20/month cell service. Yes, I even knocked my cell payment as low as possible to make sure Big Tech gets as little money from me as possible.
If a company is locked into Microsoft's LinkedIn, to that extent, with lack of ambition to use other sources, do you really want to work for them?
