I don't know who in the chain of ownership is responsible, but I won't deal with Knitpicks or any corporation affiliated with it. Several years ago, Knitpicks had a massive data breach which they knew about for several months -- but didn't tell their customer base so they could protect themselves. When the news finally broke that they were the ones responsible for a sudden rash of stolen credit information, the company was like "Oh, yeah, that. Too bad. Not our problem."
My sister was one of those affected. Her credit card company called the house to cheerfully inform her that her card was about to be cancelled and the new one should be on its way in a week or so. Thank the gods that her DH was home and answered the phone. Sister was 500 miles away at the bedside of her dying son (cancer)and was depending on that card for her motel and meals. BIL persuaded them not to cancel it, since they hadn't seen any fraudulent activity. She used to buy from Knitpicks a lot but not any more.
