I haven't clicked on that link, but I get your question. I've known communities that are paywalled. Instead of thinking it as a "slack channel that costs $$", the value prop is "it's a closed community whose entry is $$". There have been vBulletin forums where if you were a paid subscribers, they got you access to subscriber-only subforums. Couple of examples currently: 1. Product Management HQ community: $25 to join. Slack channel is there as well. https://www.productmanagerhq.com/join-the-community/ https://www.productmanagerhq.com/join-the-community/ 2. Product People Club: [it was paid. don't know current price. entry seems closed right now]. https://productpeople.club/ https://productpeople.club/
