The problem is the business model; managing all these common services is a big deal and takes serious engineering effort to keep online. You then fairly quickly should enter into relatively high prices to make this cost-efficient.
The cloud providers, however, have a trick: they can eat these costs and make serious $$$ on the actual compute, storage and bandwidth.
If you’re trying to compete with AWS et al based on price for bandwidth etc “but with common services such as S3”, you’re gonna have a really hard time convincing a customer your expensive managed Kafka is reasonably priced. And then you’ll just find yourself competing on just VPS servers...
