Twitch takes 50% of all subscriber revenue. Despite the change to local pricing, they still take 50%. So, this tier's for Chaos Crew members who want to to keep all their Twitch subscriber benefits, like emotes, sounds, no ads. This just tops up the loss of revenue caused by the local pricing changes.
This tier is the same price as the new local priced Twitch subscriptions. If you don't care about the Twitch sub benefits like emotes and no ads, then you can support here instead, and I'll get the full amount (minus some teeny Ko-fi fees).
