I haven't highlighted anything here. I actually characterized the original comment as a "low effort partisan comment".

This development is also not a counter example - Both parties routinely do the bidding of corporate entrenched interests, but they market it in different ways. So an instance of Democrats advancing the corporatist agenda isn't some gotcha like you're making it out to be.

Though perhaps by "undermine" you just mean it's something for other partisans to latch onto to support their own rationalizations rather than coming to terms with that "broader narrative".
