Dee Snider triggered controversy when he posted on social media disputing Ozzy Osbourne's songwriting contributions, suggesting that other musicians like Lemmy and Bob Daisley had authored material credited to Ozzy across his solo albums and Black Sabbath records. Snider's comments prompted Kelly Osbourne to defend her late father publicly, accusing the Twisted Sister vocalist of attempting to diminish Ozzy's musical achievements and legacy at a time when he could no longer answer the allegations himself.

Snider subsequently sought to defuse the row by expressing his affection for Ozzy and acknowledging Black Sabbath's formative influence on his own career. He attributed his scrutiny to a personal sensitivity surrounding songwriter credits and royalties rather than an attack on Ozzy's abilities. Snider has now issued a direct apology to Kelly, stating he regrets that his posts caused her pain and expressing remorse for his remarks.
