How do gaming platforms feel about software licensing?

Question

Game development

Primarily interested in steam.
For example, if the game was made in a hacked (not licensed, in violation of the license, etc.) version of Unity?
Or were components/textures/technologies/software without licenses (cracked programs) used in the creation of the game?
This is not a clear violation of copyright - I took someone else's texture and used it in the game. It's about the licensing of development tools.

Of course, when you launch the game, it will be difficult to prove that the game was made using non-licensed software. In theory, it will be possible to assume that the animation is made in Spine 2D, the interface contains standard Photoshop effects - but this does not say anything about the license.

Do gaming platforms require proof of license for development tools?

Answer 1

Gaming platforms - do not require. But if there is income, then the same Unity can check the license.

Answer 2

The interface contains the standard Photoshop effects - but that doesn't say anything about the license.

Dude, a single file made in a pirate photoshop will tell you everything photoshop can get its hands on about you. Especially if you open it in a real, legal version. There will be such an abyss of information that you will be surprised.
I don't know how Unity licenses its development tools, but given the trends, they probably knock too. Moreover, even if the platform is sawn and does not knock on its own - one day the file will be opened on a real, licensed platform - and all the accumulated information will be in Unity.
(I can’t say exactly what is happening. But global trends are such that this is most likely the case)
Most likely, as long as your game is bought by a hundred nerds and is worth the price of a bus ride, they can score on this. If there is a project of the Battletech scale, there will be a fight for every texture.
