I believe she's more upset that they didn't get to do much with the titles while they had them. All her title reigns have been extremely short. Sasha and Bayley haven't really been played up to their strengths on the main roster. Look at how amazing their NXT runs have been compared to this.

They're friends with the IIconics, and honestly there was no other team on the woman's roster that deserved to be the next woman's tag champs other than them.

They're not using her properly though, at least not as well as they should. I'm almost starting to think Vince hates wrestling and would rather just have a show full of acting eventually.
