Have you thought about looking for a job with a tech related non-profit? I joined one a few years ago after spending my entire career in the traditional for-profit tech space and I have been amazed at the difference between the two worlds. Most of the negative aspects of the VC driven tech world that you talk about don't really exist in the non-profit space. It's not all sunshine and roses, but might be a great way for you to get back to what you used to love as well as contribute to something meaningful.
