I know many who have had hugely successful exits to vista. They are extremely good at what they do - but perhaps what they do doesn’t align with your morals
If drop in quality and increases of price for the same product is good morals, I question the supporting worldview.
"Profits above all" is not a good thing. Authentic delivery and growth is a great thing -- it means people want your product. Profits above all is just pillaging.
I've heard multiple horror stories from founders who sold to Vista. They don't exactly have the best reputation.
I wouldn't be surprised if this move stripped value away from other stakeholders in some slightly questionable manner.
