Messaging interoperability between the two major mobile platforms greatly affects communication for those of us who have friends and family on the other platform. Cross-platform messaging allows us to communicate no matter which platform the friend or family member happened to buy. Blocking this feature is anti-competitive and detrimental to communication.

The entire purpose of government is to help make society better for all of its members. Some government representatives may decide that 'better for society' would be to allow the corporation to maximize profit even if it harms the consumer. This particular politician believes that society would benefit from this interoperability and that the company may be overstepping anti-competitive monopoly boundaries by blocking it.

Whether you agree with the idea or not, and whether it affects you personally or not is immaterial. It affects society at large and the government is supposed to represent members of its society.

It's nice that you either don't use SMS or all of your family/friends are on Android, or you simply don't have family/friends, but for the rest of us, we would like to send pictures to our grandma without her complaining that it's pixelated and tiny because she has an iPhone. It has been frustrating for years, but now that a solution has been realized, it seems anti-competitive that one of the vendors is now trying to block the fix. Regardless, even if this fix remains blocked, we do have hope that iOS will get RCS in the near future.
