I think it's more about the bait and switch marketing optics of offering a "core" part of your codebase as "FOSS" to get the extra brownie points by doing so, while it's at the same time littered with caveat emptors, and imports from "enterprise licensed" code for the features that business care about.

Also all the "commercial open source" or COSS seems to lean into that, its a valid strategy to monetize open source, but should be done transparently and being very upfront about its bait-y nature to businesses or enterprises imho
