It's a completely personal thing, but I'm pretty good at separating the art from the artist.
I mean I love listening to Bowie's music, he liked the girls younger than legal age (he slept with the Maddox girl Jimmy Page kidnapped and kept hidden in his room for years before she got involved with Page! In fact, by her account, Bowie took her virginity). I like The Stones even though Bill Wyman married a teenager and was by all accounts somewhat of a predatory creep too. I still like Led Zep regardless of Page's sleeziness. Etc. etc.
Plus, I've always thought Ryan was a complete and irritating self-centered prima donna total and utter knobhead anyhow.... he's elevated his level of dickishness in my eyes, but I had already disassociated his music from the man from the word go.
So yeah, Ryan's music doesn't change for me, but I wholeheartedly and unequivocally condone any of his behaviour described in the article... all of it is evil and wrong and I hope he gets hi comeuppance for that, and I hope he can be a strong enough person to admit he's royally fucked up their lives and can seek help to heal himself and to prevent anything like this in the future.
