I would like to warn others about the fake Audacity app in the App Store. If you’re using an iPhone or iPad, please DO NOT download Audacity Audio Recorder App. I wasn’t aware and downloaded for my iPad. When I launched the app, I was forced to sign up for a subscription and unable to close the pop-up window.
In the app page, please click “Report a problem” to report this as a scam/fraud. If you have subscribed to it accidentally, you can go to https://reportaproblem.apple.com and request for a refund.
I don’t think they can. It’s up to Apple what they sell from their store. I assume that if enough Apple customers complain and ask for refunds, then Apple will take it down. Similar problems exist on ebay, Google, and Microsoft Store, but sadly they take little notice of open source software developers unless the developer has the time, money, and expertise to sue them. Audacity users can help by complaining loudly to offending parties.
