I disagree with the notion that oss is used as marketing bait.

a) offering paid support for bespoke selfhosted installations is an entirely different business model than building a managed service on your oss offering

b) maintaining k8s/helm charts is work - who is paying for that? The selfhosting users certainly aren’t and usually contributions are not enough and even then still need reviews.

You think it’s a deliberate choice. Yes it’s the choice between going out of business and continuing.
