It was fun thinking of these, I actually put together a blog post a while back listing my favorite software. Would love to revisit it soon: https://lukemil.es/blog/software-i-like
And for those who don't know, youtube-dl supports many, many other sites besides YouTube, including Vimeo, TikTok, Dailymotion, Twitch, YouKu, LiveLeak, Streamable and more.
I'd be careful with package tracking. While I don't know if that particular app resell your purchase data. That one is paid, so they may not need to right now, but they may change that in the future. I know many other similar (Slice, Unroll.me, etc.) products do. It's an easy, high ROI monetization strategy.
Apart from Arch, Fedora and [insert your fast-paced distro here] I wouldn't recommend to use the package manager's version of youtube-dl, because it's almost always too old.
