What do you mean? Can you describe a scenario where this MinIO license matters?
Obviously the fully-managed nature of S3 is very valuable compared to MinIO but the licensing issues seem neither here or there.
Rolling your own storage comes with at least some operational expenses, if you’re counting your data/egress in gigabytes that’s likely not worth it compared to just using S3 or similar services.
The durability can have value at scale, because ensuring it at scale with MinIO can be a lot work. But I often recommend to clients that they deploy a Hetzner setup as a cache, often with storage all the way up covering 100% of their data depending on access partner, because the AWS egress fees are so insanely extortionate that you never really want to read data from AWS at scale other than as an emergency option.
K8s probably means more s/w than hardware, more bodies (for them) more helpdesk and more documentation, more process. More up-front cost. And, they seem to be making money without it. Maybe thats their position?
AWS launched it before EC2 even it's that valuable.
