I'm not sure how you expected to avoid this.

Because I deleted my account immediately upon learning about the disclosures. I assumed the notifications would come via email or SMS. They've never had trouble doing that before now. For FB to turn this into yet another data collection vector, as well as tricking people who may have “deactivated” their accounts into logging back in and stopping the deactivation process, is just the height of evil absurdity. This is beyond the pale even for them.
