He's very much not saying this, he's saying he doesn't want a small number of very large companies to be in control of whether or not his skills are valuable at market. This could broadly be construed as an argument against the entire cloud/SaaS/PaaS/IaaS market, but it is still a very valid criticism. Most IT people are in some way subordinated by massive companies, and free/open source software is an escape hatch on that, because there's not a relationship of exploitation or control between users and community projects.

This is not at all what he said, he refuses to use (learn) it because of ideological reasons. That is not the same. I can relate to some extent.

I refuse to learn anything about any propietary technologies unless you pay me for every minute I spend doing it. and I'll probably get right on to forgetting it if you stop paying me, but won't really cuz my memory and experience are mine and Severance (tv series) is still fiction

WhatsApp isn't something you have to learn.
