As OP specified in another reply, they were talking about streamers specifically. And with them, big chunk of the income comes from Twitch subscribers, which is a monthly paid subscription. If you are willing to pay someone for it, you’ll notice pretty much immediately if they miss their scheduled stream and cancel it.

For many other platforms what you said is true, I’m way more likely to unsubscribe from someone when they post a video and remind me I’m still subbed than when they take a break and fade out of my feed.
