If you mean Komai specifically, I think that this characterization is unfair.
Komai is explicitly presented as a fork of Nheko. We credit the upstream project, major libraries (matrix-sdk) and assets (iconsets, etc.), and are open about using AI during development.
I’m not claiming sole authorship or pretending Komai was created from scratch. It's built on existing work (done by various humans over many years) and we're being transparent and thankful about it.
Disclosure: I've spent multiple months working on Komai (with AI and other humans).
