Your comment's parent might know very little about ADHD, but your critique shows an antiquated view as well. It's not only the ADHD person that needs to change by any means available so that they fit the expectation of the system. The system, too, is in need of change, so that we accommodate more diverse people. Improving the environment that you operate in goes a very long way and might enable exactly the kind of change that makes children and adults with ADHD thrive. Medication is just one option. CBT and more flexible environments are as important, probably even more so.
It's not an either/or thing. At least for my kid, it's been a combination of the 3 that have helped, but if you dropped a component (including the medication), she wouldn't be doing nearly as well.
I agree with the label being a huge problem. It's basically compressing a multitude of individual characters with huge differences on multiple dimensions of behavior into a binary label, which people confronted with someone bearing that label then decompress based on their personal view on the topic, which is like an algorithm trained on caricatures of what society portraits as ADHD. Your comment sounds like you're doing the same mistake: you take your favorite solution for a complex problem, which (I agree here!) might actually be sufficient for some, a relief for many, any at least good or not harmful for everyone else, but you try to market it as the only necessary solution while invalidating everyone's needs that go beyond this solution. It creates the reactions that you can see in already a handful comments that basically call for the individual to accommodate to the system at all cost...
