Yes, and like hormonal imbalance in cis people, the evidence is clear the benefits of the treatments outweigh the risks also for trans people. This is how we make medical decisions, not as a proxy for moral panic.
The only disingenuous framing is hormone blockers as "transition".
I'm extremely cynical about Amazon's move qua their own ethics, here but I also understand where the internal pressure is coming from given how rapidly the UK mainstreamed such deep transphobia.
