All non-idiots believe in a mixed market economy. What sectors of the economy are socialized, what are lightly regulated market based, and what are heavily regulated market based are and will be forever matters of contention with which reasonable people can agree.
I have no idea why he would think it's immoral for Facebook to have an HQ other than a 'everything should be socialized' short-sighted ideology (I also didn't read or watch the article), but the general complaints he had about Big Tech in Rojo's quote are spot on. And Facebook is the worst, since at least the other monopolistic big tech companies (e.g. Google / Amazon) provide a social good (i.e. create wealth) with their products, even if their monopolistic practices (should) require them to be broken up / nationalized / heavily regulated / whatever solution you prefer. Facebook (and all social media) is a public menace that needs to be made illegal or regulated to the point that it's a mere phonebook replacement and its stock crashes; social media tech companies are basically dopamine drug dealers that are capitalizing on the laws not moving fast enough to regulate what it does. (It sells your data and tries too hook you into giving you more of it by literal addiction; Cambridge Analytica isn't an outlier, it's a representative sample of the entire reason Facebook is valuated like it is.) Social media is **EVIIL**.
Also the whole reason it's so ridiculously expensive to live in the south bay (really most of the bay area) is that their building codes won't let supply catch up with demand.
