The detriment to society came when the standard for text messaging between all phones was updated to support more features and a major manufacturer intentionally didn’t update to drive sales. The US used to heavily punish that sort of behaviour, but in this case it took EU Chinese action to reign in a US company.
Samsung, Google, Sony, and a million other manufacturers could have implemented their own messaging system, but instead they chose to facilitate the use of devices however customers want without punishing them based on the personal preferences of their friends. In some circles people may even choose not to communicate with people who don’t have iPhones or exclude them from group chats which is bad in just about any way you spin it.

FWIW in this case it was Chinese action - China is requiring all phones sold domestically to support RCS. The EU DMA would have forced Apple to open up access to iMessage, not implement RCS, but they found that in the EU, iMessage market share is too small for the DMA to kick in (probably due to the overwhelming popularity of WhatsApp).
