It's sad when people copy another person's work and try to pass it off as their own.
This happened last year to a developer. Reported to the developer and it got removed about a month later. The developer used to sell their game and put it up for free for a while and someone copied their Itch page and game and renamed the game and was selling it.
This also happened to another Itch developer, they have a game here on Itch. Some scammer took their game and put it on the Windows store and was selling it. After reports to Microsoft by the developer and people, the game was removed from Windows Store.
Sadly, some people are scammers and will take another developers game and make a fake page making people believe they developed the game. Or as what happened to the other developer, a person took their game and sold it on Microsoft store and tried to claim that they developed it.
