I think OP's comment comes from the "Think Different" mysticism that used to be around Apple. You'd think that if there was one company on the planet not embracing slop, it would be Apple, and the realization that it's not the case can be a bummer.
"Slop" means low effort/low accountability. It is independent of the tools used in development.
"slop" and "vibe coding" are derogatory terms about the level of effort - e.g. little to no human review of quality or accuracy, or accountability/concern related to the output.
