What they want is a couple of big, reliable companies who offer services that just work. They want dev teams to be able to explore a new service by simply spinning up a POC with a new offering from a vendor they already have a relationship with; they don't want to figure out which of the 20 different EU companies who offer LLMs or managed Kafka they need to contact, sit through sales calls, and do security evaluations on before the team can start work.
As an American, I definitely don't like having to drive to a mega store and do all my shopping there. The European city model is far superior -- I love traveling there and walking to the bakery, cheese shop, and butcher to buy a meal. But as a dev and manager of many years, I definitely do not want to see that be the norm in software. I love startups who offer unique services, but from a practical perspective, I also love that it takes a day to spin up something in AWS vs months of contract negotiations, trials, sales calls, etc to get signed up with a vendor who offers something outside of AWS.
