Interesting discussion altogether so thanks to the OP, and appropriate contribution, thanks to you for that.
Note Pondsmiths repeated use of "not just" and "everything about punk" though, indicating it is in fact all these things too. I was part of the punk scene (which does still exist btw), and I'd say it was and is extremely difficult to define, no dictionary does it justice now, for instance. "Personal Rebellion" is certainly a major tenet, and can be easily pointed to from the start of the movement, e.g. the rejection of the then mainstream of communal hippiedom, but many of it's major personalities went from individualist impresarios to cult, even corporate leaders and stooges, e.g. Malcolm McLaren, Vivienne Westwood, and the masses itself became a spectrum of society as a whole, everything from nazi punks, through yuppies, fashionistas, romantics, ecologists, to anarchists... which pretty much brought the movement back to the very thing it was born to reject. So Punk is also hypocritical. That's life, eh.
If I were crazy enough to attempt a short definition it would be this, Rejection of the Mainstream. The current mainstream, always. In current PC gaming terms perhaps such rejection would be elevating story over dopamine high gameplay, graphical considerations, even the open world paradigm - for these are the current mainstream. Controversial I know, but since we're discussing putting the punk in cyber, then it's the natural progression of the thought.
Must admit OP, I'm a bit concerned about the music myself, I would've expected electropunk synthwave to be... a solid option.
Oh and, I know you don't mean this Eddie, but it's entirely apropos.
