YouTube Shorts copies TikTok again with voiceover narration

What's the best way for YouTube Shorts to take on TikTok? Apparently, it's by continually copying its popular competitor. Yesterday, YouTube announced (via TechCrunch) that it would be adding voiceover narrations to Shorts on iOS. It'll let you add your own commentary on top of existing videos with just a few taps. That's simple enough, but it's also something that TikTok has offered for a while, and it brings to mind Instagram's repeated attempts to copy TikTok's core features.
