Although, I wonder if there has been an effect on OVAs.
Well, there's just less OVAs made in general, whatever the reason. Overall it seems like nowadays the 1 cour TV series has taken the place of the ~4-8 episode OVA. I doubt we could really determine if there's a relation to piracy, or whether the TV 1-cour model is just more profitable/easier than the OVA model overall. Regardless, I'm not a fan of OVAs so I'm not lamenting their decrease.
Any sales analysis of OVAs would be pretty hard because I imagine a significant percentage of them do not rank, and didn't in the past either.
