I agree with you FWIW. The company also basically doubled in size from 2019 to 2023. It's very hard to grow like that and experience zero changes. And COVID happened shortly after so that also throws a wrench into the comparisons.
The point is, it's hard to point to any particular decisions or changes I disliked and say "IBM did that"
Cormier and Hicks have their strengths. Hicks in particular seems to care about cultural shifts and also seems adept at identifying key times and places to invest in engineering efforts.
The folks we have imported from IBM are hiring folks that are attempting to make Red Hat more aggressive, efficient, innovative. Some bets are paying off. More are to be decided soon. These kinds of bets and changes haven’t been for everyone.
Longtime Red Hatter here. Most of any challenges I see at Red Hat around culture I attribute to this rapid growth. In some ways it's surprising how well so many relatively new hires seem to internalize the company's traditional values.
FWIW, the change at Red Hat has always been hard to separate between the forces of IBM and the reality of changing leadership. In a lot of ways those are intertwined because some of the new leadership came from IBM. Whatever change there was happened relatively gradually over many years.
