One of those two sites is distributing adware. Which of them?
File Converter (FOSS) by Adrien Allard was hosted on file-converter[.]org since a decade. Then someone a few weeks ago snatched that domain and it’s now distributing adware. Almost identical design for the page, 100% designed to deceive users to download a different product, as it’s called Zamzar.
In the github issues the dev is aware of this but he’s not completely enraged, just mildly infuriated that the design is too similar and he’s politely asking to have a different design.
From the history in the wayback machine i don’t see any “parking” page between the switch, so my guesswork is that the dev has been approached with an offer like “we like that domain, we would like to buy it for $$$”, unaware that they would copy the design like that in order to achieve maximum deception of users
