There are still many anti-capitalist expressions from gamers and the like, but there are not enough leftist voices to frame them as such inside those communities.

I think another aspect that has occurred recently is capital corporations have cloned the socially progressive talking points of the left.

These concessions to progressive politics to court younger consumers are no challenge to the power of capitalism. Throwing corporate sponsorship at BLM, LGBTQ or environmental organisations still keeps real power in corporate hands. Allowing an amount of dissent and protest in non disruptive forms poses no threat to them (Don't block a motorway and they'll let you protest as much as you like).

However it does allow the far right to radicalize the geeks. They can be convinced that the SJWs are their enemy rather than the bosses who adopted some SJW points in the name of progress so business can run as usual. Both "sides" are still just an internal contradiction within capitalism.
