The title blurb seems to present it as a functional clone, rather than a limited copy.

"A Flipper Zero clone, but cheapest, DIY and simply Open Source, made with Arduino IDE"

Why not?

"A hobby partial Flipper Zero clone, cheaper, DIY and Open Source, made with Arduino IDE"

So it doesn't have to be clarified further down. I get that it's not that down, but the title is what will be shared and seen in web previews everywhere.

That being said, it looks very cool, and the name is fun.

That's my thinking. It's not a clone. I finally remembered the term I was looking for. It's a "demake" - a remake but worse
