Who is "they"?
And even if you are correct about "them" it doesn't make the author's point regarding the GOP under Mr. Trump any less true. The whole RINO argument is about turning the definition of a Republican on its head. Most if not all of the people involved in the Reagan era GOP would now be considered a RINO.
As to the article, the most damaging thing pointed out is that the GOP is no longer the party of limited government. MAGA loves big government as long as Mr. Trump is the leader. And Mr. Trump loves MAGA as long as they remain loyal to him.
There once was a political party leader that placed loyalty to the party (the leader) as primary over the country. Lenin/Trotsky was prelude to Trump/Massie or any other person who got on the wrong side of this president. Mr. Trump is not interested in people who are loyal to America. Since he and many others have confused loyalty to him with loyalty to the US, it is not surprising that the GOP is now nothing more than a skin suit as the author puts it.
My question is; now that Mr. Trump has emasculated the GOP who will be acceptable to the trumpian faithful once he is gone?
