It looks great, inspiring to me as a product maker getting started with blocks. Thanks for writing about block-based products. I love seeing what's possible.

Frankly, commercializing the removal of a credit link a shady business practice.

I respectfully disagree. The user gets something of value for free and the provider gets exposure. That's a fair deal in my view. The paid version does offer more value than just the removal of the credit link. If I were a betting man, I'd wager that more upgrade for extra features than the removal of the credit.

This was frowned up 10-15 years ago when theme authors were doing it. It should be frowned upon today when plugin authors do the same.

Has this changed, maybe? I've had "Powered by" links in my commercial theme footers for eight years with an included option to change or remove. These are paying users and most leave the credit in place. It's a significant source of referrals for me. If my paid users are content with it, I'd expect free users to be at least as content.

Otherwise, either my audience is different or there is a problem with the mentality of "free". Many people, when they pay nothing for a product, attribute a low value to it. More than one product creator has observed that this tends to create a sense of entitlement in some.
