So many customers don't account for this and it up costing $$$ if your data model isn't a good fit. Cosmos even takes it further w. 1kb units (I have spent hours on Cosmos pricing and am still baffled on how to price a workload.) Although... it does incentivize decent data modeling practices which often lead to more performant apps.
The loosening lens is a bit of strawman argument. I would hope someone at the level has experience with the business side of things... Pichai and Nadella weren't tapped to run their business straight after shipping a release.
Also, Howard joined in May (which is an important one...because this press release is about Cloud not about HR/patents.)
I see this type of comment thrown around a bit, but a quick pass of the senior management suggests otherwise. https://newsroom.ibm.com/executive-bios? Not a whole lot of MBAs and a decent amount of engineers.
