That's old leftist position. New left is identity-based, not class-based.
Just to clarify: I do have some respect for some ideas of the class-based left, unlike for the identity-based one. Roughly speaking, I do agree (though for a different reason) with the idea that the intellectual property should not exist.
FFS, this story itself is a perfect example. Here we have a corporation firing an employee for 'wrong' speech - and the left is in full support.
That's a class issue, and the left has clearly sided with corporations over the working class.
