Ask HN: Is there a place for MMS/SMS subscription for courses/content?

I was bored in my free time over the past week and threw together a web app that uses Twilio+Stripe Connect&Checkout to build a two sided marketplace for creators to distribute content via SMS/MMS at a subscription price they determine. Considering releasing something with it but not sure. My intuition tells me that for distributing courses content, there's already online sites (Patreon etc.) that distribute content in well organized ways, and for courses there are sites like Udemy that organize content well already. SMS/MMS does have the advantage of being placed directly in user's texts inbox, but I'm not sure if this really increases the value. Curious to hear from others if they would use something like this.
