In the abstract, I understand the reasoning on that Intercept article. If you're willing to work with people like the Lincoln Project on unseating Trump, or other mainstream Republicans on other bipartisan priorities, why not work with non-mainstream Republicans on progressive priorities?
The difference is that while that all seems symmetrical on the surface, the simple fact of the matter is that the agreement you get on bipartisan initiatives generally is not really all that much like the agreement you get between the "populist right" and progressive priorities, because their support for those things is a fiction. They don't want it in any meaningful way, because their populism is a white, cis-male, straight, non-intersectional populism. It's about maintaining supremacy not class warfare. When they talk about "the elites" they mean intellectuals and Jews, not rich WASPs on Wall Street.
Put another way, that Intercept piece is, speaking charitably, somebody falling for the National Socialist label from the other direction.
