Companies taken over and run by value extractors (finance/business/marketing) over the value creators (engineers/product/creatives) end up in this stagnated, picked apart state when the grace from the value creation or product wears off.
Value extractors need to learn that you must first create value before you extract it. The reason value extractors originally were attracted to the project/product is usually that it has created value.
R&D has very little value to an MBA so it is cut, but long term it is all the value of the company. Value extractors kill the whales before they even can grow up.
IBM is one of many, and their decline wouldn't really matter all that much in the grand scheme of things.
The changes could even be by the same people, I'm sure many from RH will not like IBM culture.
That said, Red Hat is doing well and I don't see them dying.
Disclaimer: I work for RH but opinions are my own
I would argue that this was never true--even from inception. HP was an engineering-first company--not IBM.
IBM was about sales and marketing--they would rent and finance equipment for you even way back.
Now, IBM had world-class engineering, but people forget that a lot of the major companies had great engineering until the 1980s.
It was always sales oriented and engineering was something they had to do to deliver some of the things they sold. This may be the first CEO that was actually an engineer.
Having worked for IBM and being a client of IBM in the past with large gov't agencies , i can also tell you that part of their success is liability perspective from the client. I know many of gov't big wigs who simply hired IBM not because of their talent but because if TSHTF they covered their arses with congressional hearing or lawsuits by saying what more could we do than hiring the vendor that made the product.
And that turning point is happening/happened.
