There are a few things in the RWBY series that don't add up, leading me to believe that Qrow could actually be Ruby's biological father.

1 - While Yang uses her father's surname, Ruby uses her mother's, and no reason has been given for this. While it could be to allude to her colors, it could also be because someone (likely either Tai or Qrow) wanted to hide who her actual father is.

2 - Qrow is from the bandit tribe. At this point we haven't learned too much about them, and more specifically, if there are consequences for deserting them. If there are, hiding the fact that Ruby is Qrow's daughter could be a way to protect her. And as for Yang, Raven returned to the tribe (while Qrow didn't), so the same idea wouldn't apply to Yang as Ruby. (As a side note, "Bad Luck Charm" says "You don't want the burden of my name." Although it meant his semblance,  it could also be his connection to the Branwen tribe.)

3 - Qrow's semblance is misfortune. It could have been disasterous for Qrow to raise a child with his semblance. Little children are insanely clumsy, throw in a bad luck semblance and who knows what could happen. Leaving could be a way to protect Ruby from himself.

4 - Prior to his first appearance, Qrow was always on secret missions for Ozpin. To try to raise a child alone while keeping up his work for Ozpin wouldn't have been possible, and by then Raven would have deserted Yang, Tai, and Ozpin. So between working for Oz and racking up enemies, keeping Ruby in his life as a daughter would have been hard. Even Raven said that she wanted Qrow dead. Some one could use her to get to Qrow, putting her in harms way. Leaving Ruby with Tai would allow her to be raised in safety with a good family.

5 - Not much has been revealed about STRQ's past. We don't know how the charaters interacted, if any of them dated in school, etc. It could be possible that Qrow and Summer were together at some point and could have had Ruby. And Yang is only 2 years older than Ruby. Say Raven left one month after Yang was born. That would leave about 14 months for Tai to move on to Summer and get her pregnant, so it can be asumed that Summer and Tai would have had to be extremely close prior to Raven leaving. After all, Raven had just walked out on Tai, what was stopping Summer from doing the same? At this point, we don't know if they had a close enough relationship to pull that off in the time frame.

6 - Qrow taught Ruby how to fight. In "Red Like Roses II," Summer said "Baby, please don't do what I did," meaning she didn't want Ruby to be a huntress. We don't know where Tai stood on the matter. Since Ruby was bad at hand-to-hand, Qrow was better to teach her than Tai, but if Tai agreed with Summer the only one who would have the authority to go against them would be her biological father. And it wouldn't be for the first time that Qrow did something that goes against Tai to prepare her (like telling her about her silver eyes).

7 - Other little small things. Yang bears resemblance to both parents while Ruby only resembles her mom. Tai seems closer to Yang while Qrow seems closer to Ruby. Qrow followed RNJR while Tai stayed home with Yang, and then Tai let Yang go off on her own, leaving Qrow looking like an over protective helicopter parent.

As for anyone who wants to say this can't be a thing based only on the Monty tweet, he would most likely have told us things from the sister's point of view to avoid spoilers, since he wasn't debunking this theory. So it wouldn't be a lie, at worst only a half truth, which Roosterteeth has done before. Also, when I looked through his tweets, it seemed Monty had a tendency to emphasize things in all caps, something he neglected to do while debunking the Yang is Summer theory.
