This is a very broad claim. Here is a factual refutation:

From the article lead: >NASA has certified SpaceX’s Falcon 9 to launch the agency’s most important science missions, giving the agency new options that could result in lower costs.

NASA sees reducing launch cost as a top scientific priority. The mission of Starship is to do the same.

SLS is not "for science", it's a jobs program for Shuttle contractors.

Who is the megalomaniac? Elon Musk or Richard Shelby?

Especially with the way innovation works now, one person's "megalomaniacal fantasies" can easily lead to scientific progress.
