I was hoping it was nonsense and someone would point out the errors, no such luck so far.

It's not complete nonsense, but it conveniently leaves out key relevant details and includes key pieces of misinformation needed to make the talking points make sense (as you would expect from rage bait.)

> Early on, SLS designers made the catastrophic decision to reuse Shuttle hardware

The law that mandated that NASA built the SLS also required that they re-use that hardware. This wasn't a choice made by NASA designers but by a bipartisan congress and it wasn't designed so much to advance our space program so much as a way to keep funneling money to space contractors with the end of the Shuttle program.

Any article that proposed to discuss the "lunacy" of Artemis without ever mentioning Congress's role in that lunacy is pretty clearly rage bait.

good to know, but the outlook for success is still the same? just the blame is not only NASA.

Artemis and SLS have many problems but I would look elsewhere than that article if you want an understanding of what they are and why they exist.
