Steamspy is very useful. The data from it is used by a lot of publishers as well as developers to make a case for whether or not there is a business sense in making a specific game.
Steamspy 's data reliability took a severe hit when Valve made all user profiles hidden by default and it never completely recovered since then.
It used to have a margin of error of 5% at most, even for a lot of small sellers, as confirmed by several developers regarding their own games over the years, while these days it can swing WAY more wildly. There have been cases where it was confirmed to be wrong by a factor of ten or more. And it's especially unreliable (I've been told) for anything under the 500K these days.
On a side note, while it was a useful tool to have, I can't even be sad about its downfall, given who's working on it and managing it.

Party control in Baldur's Gate 3 is a complete mess that begs to be addressed. SAY NO TO THE TOILET CHAIN
