Go down the list of big tech companies and you'll find tens of trillions of dollars of valuation – more than most other industries put together – having nothing to do with social media or advertising. Even if you remove Meta (which the article is about) from existence, "big tech" would largely remain the same.
So yes, all the concerns raised in the article are valid, but equating Meta/Facebook with the entirety of tech is idiotic. Such companies make up a very tiny slice of what the technology sector is about, and they hardly wield the amount of political influence that is suggested.
