I think a gap between wikipedia and a polemic by somebody clearly fired up about a topic is not just reasonable, but productive. Wikipedia, by nature, gives the sense that all philosophical viewpoints are equally dispassionate and it minimizes the degree to which reasonable people can substantially disagree about the rightness or wrongness of various worldviews. That usually gets dumped in the Controversy section. This is fine for an encyclopedia, but not for a debate.

Of course, I also think that OP is being polemical and that means they're not interested in being charitable. I think their criticisms are interesting, but the original post linked here does a far better job at balancing a charitable read of stoicism with a critique of why it is appealing to the rich and powerful.
