Aside: Isn't Wordle just an adaptation of the game Lingo? [1] Fun, most definitely, but hardly the novel idea the internet seems to be making it out to be.

1) Everyone in the world gets the same puzzle every day
2) The "share to Twitter" message just shows the green/yellow squares, so it shares your journey and teases the puzzle, without spoiling the answer.
Almost no one had heard of Lingo/Wordle before this, now they have, so that counts for something.
Per Wikipedia it aired in 17 countries over 35 years and counting, so it seems relatively widespread to me.
(You’d be hard pressed to find a Dutch person who hasn’t heard of it!)
Interestingly, this means that copying stuff will not come back to bite you, even when you get popular - as long as you copy ideas and not assets/characters/etc.
