The man who killed Google Search?

It's a ridiculous term that promotes polarization and dumbs down the level of discourse. I have the same reaction to it as when I see "bootlicker" as applied to anyone who takes the company's side (or is in management in general). There's too much adversarial name-calling these days, and not enough seeking understanding.

If you also take a wage, then you're also a class traitor by any reasonable definition, because denying the existence of class struggle only benefits capitalists - https://en.wikipedia.org/wiki/Class_conflict

It seems like you might be abstracting and dumbing down the meaning of the term.

There was a sense in which the author uses that term as an abstract and meaningless insult. But there's also the sense in which the author uses the term as a reference to the class struggle, and the fact that scientists are generally in a lower class than capitalists, and so should, in theory, owe their allegiance to worker class rather than the capital class.

All of this nuance is implied in that statement. If you see class traitor and don't immediately think about arguments about the class struggle between capitalists and workers, then you are in effect infantilizing the term.

You can claim that a large part of the audience will naturally react that way to this term. However it may be the case that the author does not care if people who do not believe in the class struggle would tend to infantilize that term. Speaking to the audience that knows about the class struggle theory is sufficient and valid.

Thanks for helping me make my point. How's it up there in the socialist ivory tower? See, I grew up in Soviet Union and seen socialism's effects first-hand. It thoroughly disabused me of the notion of the holy class struggle and made me an unabashed capitalist (though I imagine our definitions of what this implies will differ).

It only "promotes polarization" if you have already decided that anyone who uses it "dumbs down the level of discourse." If you instead give them the benefit of the doubt that they're trying to make an intelligent point about a situation or dynamic, and then try to understand that point, and then reason about that point's validity, then you will finally find yourself actually engaging in the "level of discourse" that you purport to (but are actually undermining with your kneejerk disdain).

Capital is Other People's Money (OPM) and capitalism is crafted so that's what rules.

Comparatively, socialism is other people's labor. That may be all you can do if there are not many other resources.

Free Enterprise is something completely different altogether.

For the Soviet natives I've known who have come to the US, it has often turned out to be the Free Enterprise which was the most promising thing they found which was not in their previous environment.
