Paraphrasing a tidbit of information from Northwest Repair, who’s a guy on YouTube that does board-level repairs on computer hardware:
Apparently, reprogramming the firmware config and changing the RGB light status on a DRAM module are both done through the same SPI bus. Consequently, every time you change the RGB lighting, it has a tiny chance of accidentally bricking the stick.
So not only is RGB an additional upfront cost that consumers might not want, it could even contribute to long-term costs by reducing the lifetime of some components.
Imagine if ransomware did a BYOVD and held your actual hardware ransom.
Shit like that should never have been signed by Microsoft, let alone made it through developer review at Gigabyte.
