If anything, they are playing on similarities to Stadia (even adding a keyword in the repositorys keyword list). I found this issue talking about the name: https://github.com/netrisdotme/netris/issues/48

• Name is confusing, sounding either like a TETRIS clone or some type of network tool (other than "game streaming").
• Several preexisting projects on GitHub share the same name, not helping beating the confusion of the name. Not to mention other companies or software projects globally using the name already (a quick Google search will show up Netris VPC for example).

And this response from a dev (only part of it): by wanjohiryan

Regarding the project's name, you've raised some valid points about potential confusion. While it's true that different entities can share the same name without issue in non-competing sectors, your concerns about clarity and uniqueness are well noted. We'll take a closer look at how our project name might be perceived and consider the possibility of a rename to avoid any confusion and ensure our project stands out.

But I don't know, together with the rest of the reply this sounds a bit robotic like from an AI. I'm probably wrong here, but nowadays can you blame me for that? Whatever. My point is, they may even change the name if they are serious about this topic.
