Why do I have to pay for a plan to use my Adobe Fonts? Doesn't make sense to me

If is not a joke, I really want a long explanation

Here is my site Read-Only: LINK

2 different companies & Webflow doesn’t earn anything off of your adobe subscription.
A free plan normally has the purpose to convert you into a buying customer. You can’t expect unlimited features for free.

Not a webflow employee but the answer to your question is quite obvious is my opinion.

Best & good luck.
