fwiw I was always pretty transparent about our priorities:

We enable self-hosting because not everyone can use a cloud service (e.g. government regulation), otherwise we probably wouldn't even spend energy on it. We dont commercialize it at all, and likely never will. I strongly believe people should not run many systems themselves, and something that monitors your reliability is one such system. The lesson you learn building a venture backed company, and one that most folks miss: focus on growth, not cost-cutting. Self-hosting for many is a form of cost-cutting.

We do invest in making it easier, and its 100% a valid complaint that the entire thing is awful today to self-host, and most people dont need a lot of the functionality we ship. Its not intentional by any means, its just really hard to enable a tiny-scale use-case while also enabling someone like Disney Plus.
