Disclaimer: I have no quarrel with the mods using the term in the creation of this community. I understand why they chose it, as even if they share my disagreement with the term when applied to ADHD, there's not really a better inclusive term. "Mental illness" is really the only other option, and naming a community that would probably invite darker discussions that the mods might not be prepared to handle.
Another disclaimer: I think the term is perfectly valid when applied to autism, as autism is not, to the best of my knowledge, a mental illness so much as a difference in processing. Being autistic is only "bad" in the sense that our society discourages autistic traits. (Apologies if this is wrong; I'm neither autistic nor especially knowledgeable about autism.)
The term "neurodivergent" implies that there's nothing wrong with you if you have ADHD--you're just special and different. But my ADHD is an illness that requires treatment. A lot of people will tell you that the only reason ADHDers struggle is because society is set up wrong, but I don't think that's true, at least for me. Being unable to remember anything, unable to self-start, and hypersensitive to rejection would be massive problems in any world. Sure, the world today is particularly brutal for ADHDers in a way we could probably mitigate if we reorganized society to be kinder, but that doesn't mean ADHD isn't ultimately a disorder that some people need to treat with medication and therapy.
Right out the gate, I don’t like the ‘superpower’ narratives or the ‘something we should get rid of entirely’ ones myself for both ADHD and autism, as someone with both.
First off, I agree that therapy can be big. The difference with ADHD coping methods is that I’ve found the ones have therapists recommended me generally helpful or well-intentioned neutral, while the vast majority of the autism ‘coping methods’ I’ve gotten have ranged from unhelpful to legitimately harmful.
Second is the medication point; some people don’t want or need medication, and that’s fine. Some others might not have a choice either way. I don’t have as many options there when it comes to ADHD because of anxiety and vice versa, so I might never have the option of having my ADHD mostly or completely treated through medication.
I mostly feel like it’s up to the individual. I kind of see the term as a net neutral and quite situational. I’ve found reading through the replies here to be quite interesting!
