So I think these services always take the wrong approach. Instead of promising to make the ADHD disappear or take a disciplined all-or-nothing blocking approach, they need to consider the fact that people with ADHD are aware that it's a thing they have to life with and generally try to optimize their lives to best cope with it.
So any such company should probably take on whatever tasks one has to do in life to survive in general and try to make all of that more accessible and disability-friendly to be of most help.
And we still live in a world with a lot of stigma, the ideas that adult ADHD isn't a thing or that medication is outright bad or literally cheating in life, or that ADHD doesn't exist or is overdiagnosed. There's A LOT to tackle in this lane.
