Button I'm planning on giving out, thoughts?

Rip, Alright, I'll move on to some other button then

With enough modification, it would be "legal".
The only issue is that it would require completely recreating the logo in such a way that there is a very clear difference between the original and your creation, but then you miss the point of creating a "parody" button in the first place.

Because you wouldn't be selling them (at least, I assume so) and they wouldn't be very widely distributed, you fall into a bit more of a grey area.

If you really want to make a "STEAMBorks" button/pin, you could find a similar font and write the name near the top, and them outline the entire image with a ring gear.
