As I understand, genetic counselling in the case of HD is people telling you over and over again not to get tested. One of the constraints on fertility treatment if you're at risk is that you can't have any procedure that removes the potential baby's right to choose whether or not to be screened.
But in summary:
I've decided (having thought I definitely wanted to know) not to get tested. I'm glad there wasn't a button on 23andMe I could just click to find out. It's a complicated decision, should require some thought, and has life-changing consequences. While I'm strongly pro-choice, I also don't think 7-11 should be selling abortifacient drugs -- just because technology can make some decisions easy to execute on, doesn't mean they should be as easy as clicking a button.
