Depends on where you live. It's not mainstream in the big tech cities. It's not mainstream on the American internet. "Racism" is also arguably not mainstream in most American cities, though there are plenty of accusations that certain areas are still indirectly or implicitly racist because it's a very subjective term.

Racism is expressed by systems that benefit some to the exclusion or detriment of others, based on race.

Remind me, what are the "mainstream" demographics of big tech companies?

Tech companies are famous for externalizing their problems into their local communities. How is that expressed in terms of race?

Capitalism simply doesn't work without an underclass. Capitalism exploits labor the most efficiently with a divided underclass, because class awareness and solidarity undermines capitalism. As such capitalism is invariably paired with racism. Every capitalist economy is built on some form of bigotry.
