Others would disagree that this is exploitative because they believe that wages should be set by the market.
It's clear that workers are not compensated for all of the value they produce, and that the excess value goes to owners. The disagreement is whether this is exploitative. Leftists argue that it's not fair for owners to capture value without contributing any work. Rightists argue that capital is a scarce (i.e. limited) commodity, so owners deserve to be compensated for providing capital. Who you agree with is up to you to decide.
Pg's blog post strawmans "exploit" because he uses a different definition of exploit than leftists use. This might be because he misunderstands leftism, but the cynical believe that he is deliberately strawmanning them for his own gain (since pg benefits from capitalism). A more honest blog post would examine whether value going to owners or founders is exploitative or not.
Nowhere did I state that all leftists are communists. In fact, seizing the means of production is also a socialist idea. One key difference between socialism and communism is that communism abolishes all private property in addition.
In leftist circles in the US, leftism colloquially refers to people who advocate for some form of social democracy, with most leftists supporting at least socialism. Those who support more center-left policies (like Keynesian economics and the welfare state, without advocating for socially democratic programs) are called "liberals," not leftists, despite the fact that they are left-leaning (in the US's sense of left-leaning).

> Moving left doesn’t necessarily make one “more liberal.” At a certain point, the traveler leaves the province of liberalism for one that is more correctly identified as socialism, radicalism or leftism.

> Leftist: They believe the free market system is inherently flawed to favor the rich and powerful and believe that the government should either work within the framework of the market system but heavily regulate it and pay for more social services and welfare through higher taxation on the rich and corporations (social democracy) or abandon the free market all together in favor of socialism.
> Liberals are socially liberal and typically believe in democratic capitalism and the welfare state.
> Leftists typically believe in socialism and are against the ideas of capitalism.
