1. Subscription: Moving to a subscription was a hard decision and we thought about it for 2 years, but it allowed us to focus on producing more content and improving workflow features like a figma plugin, global color editor, CSS color editor etc. I wrote all about it in a Medium post.
2. Thanks for letting me know that the licensing isn't as clear. You're absolutely right in assuming that your customers can continue using the icons even if you cancel the subscription.
