post-Gundam cryptographyfun update on the breast implant brand i decided not to go with: apparently the Motiva Ergonomix US warranty only applies to cis women.
someone i know on Discord reported that when she went to the patient support website to sign up, it hit her with a checkbox requiring her to affirm that she was cis. she wasn't told any of this before surgery, it sounds like her surgeon didn't know either (same one i used, in fact), it's nowhere on the Motiva website that i can find, and it's a bit late to switch brands now. so no warranty for her. surprise!
