It's not an issue for me, but even if links were an issue for me, I'd not use it because I don't have enough information on what it signals or what it does. I suspect that a lot of people have taken out perfectly harmless links with it. Don't wish to join them.
(And yea, a lot of the people screaming about the disavow tool were the same ones screaming for it before it was announced. But I wasn't one of them.)
