Do you think you will die if you don't buy "groceries and many basic things."? Is it an issue that all "personal software" doesn't evoke enough of a perceived value compared to those two categories?
The relationship between health and software is less tenuous than it may seem. We spend so much of our time using software — it can have a significant effect on our health. See studies that explore social media use and its relation to depression, anxiety, suicidal thoughts, etc.
Big food and big software are similar in that they are cheaper to mass produce, more effective to advertise at scale. As such many people are trapped into assuming there are no alternatives. You may never develop an understanding of what it is you're being fed.
