Well, I have a theory and I don't know if anyone has said this since I have not read everyone's post.

It's obvious that Taiyang and Raven got together and had Yang. Now. Summer may have been in love with Taiyang from the beginning. She may have tried to fill in the hole that was left by Raven but couldn't although Taiyang may have fallen in love with her eventually. This would have pushed Summer to Qrow, who is in love with her. Thus, having Ruby. However, both parents or just one may have thought it was a mistake, and Summer went back to Taiyang. Of course, all the parents figured out or were told that Ruby belonged to Qrow and Summer.

Yes. Monty Oum had stated that Yang and Ruby are half-sisters, but since (I am sorry) he is no longer around (may he rest in peace) the new creators may have changed the characters' backstories. In addition to this, Monty Oum had also stated that Blake and Adam only had a student/mentor relationship but that was proven to be no longer the case, since they were in a romantic relationship before Blake left. In the last episode of the volume 3, when Qrow asked to talk to Ruby alone, there was unnecessary tension between Qrow and Taiyang. That tension may be because Qrow went against Summer's wishes to teach Ruby how to fight, but that would and should have faded due to the choice being Ruby's. Although, Taiyang seems like he would respect his children's wishes. Furthermore, Taiyang teaches at Signal Academy, which he could have easily stopped Ruby from attending that started her career as a Huntress.

Besides, if this theory is true, the sister-bond between Ruby and Yang would not change since it is a big part of Ruby's and Yang's personalities. And it would give an arguably larger depth emotionally and plot-wise to the family's backstory.
