Because they reject the title “Mother of God” — a title which is Christological. It is about the Blessed Mother only in a secondary way; the importance of “Mother of God” is that it tells us who Jesus is. For those who want to know.

I will disagree with your expressed opinion for Biblical reasons:
1. God never, ever uses the title Mother of God.
2. No Apostle ever uses the title Mother of God.
3. No Christian writings, artwork or historical works ever us the title Mother of God before 100 AD. As such, it is certainly not the Apostle’s teaching.
4. The identity of Christ as God doesn’t rely on this title in any way.
5. Since the title is never used in Scripture, it is unnecessary to “tell us who Jesus Christ is.”
6. It is one further step in making Blessed Mary into an idol and demigoddess, instead of the humble servant of God that she is - flaws and all. God honored her in exactly the way He chose to do so. We should not do less. We should not do more.
Best.
