Just a guess, but it depends upon the customer base the specific camera is aimed at. RAW files cannot be viewed without specific software that can interpret the file and every camera model's RAW format is different from every other camera models' RAW format (i.e., RAW is not a standard. Or even an acronym). RAW files (obviously) take up more space in storage.
So for a casual snapshot photographer that doesn't want to do further processing in a RAW converter, would prefer their phone/camera card not run out of storage quickly for photos, or just wants to text a picture, and above all, who doesn't want spend time dinking about in post-processing, then not having RAW capability is desirable.
For a camera manufacturer, JPEG shooting actually offers them more control over the final image. JPEGs are always processed through the camera's image processor, and that's where they can add tweaks like lens correction, color correction, dynamic range manipulation, sharpening, etc. And that, in turn, can make the camera's capabilities look better than the RAW files. Nearly every newb, the first time they shoot RAW, are disappointed at how the files don't look as nice as the JPEGs they used to get.
