The blog author founded altinity. Altinity's main product offering is a hosted clickhouse service. The top 10 committers to clickhouse all seem to be clickhouse employees. Looking at altinity on github, they contribute much less open source. If clickhouse the company are spending 40%+ of their money to build the product, then others including altinity spend 5% dev and 80% marketing, they will get more customers. That isn't sustainable. How do you solve that? Other than fencing off exclusive enterprise features.

Yeah, so, if maintainers started blocking external contributions for business reasons or changed the license of the upstream repo, that would be a legitimate concern.

If this blog post raises any legitimate concerns, I missed them. All I see is entitlement to continue get work for free. If you're concerned about gaps in ClickHouse functionality, maybe pick up the slack and contribute back?

It takes a village to raise a database, as the saying goes.

AFAIK, the author is indeed trying to contribute back, that is the whole point: https://github.com/ClickHouse/ClickHouse/issues/54644

In 4 years, the author has raised 6 issues and zero PRs. The latest issue was raised last week to inflame this same argument and is 4x longer than any previous issue.

I don't know him but most of his GitHub activity seems to be contributing to the ClickHouse ecosystem, including popular projects like this one: https://github.com/Altinity/clickhouse-operator

My point is just that he doesn't appear to be someone complaining and not contributing.
