I have no money and a very shitty laptop, and thanks to Google Colab's free, hosted Jupyter Notebooks I'm having a blast learning Keras.
I'm not saying they're saints, but they've given me something free that's improved my life. Maybe it's ultimately greedy in the sense that later if I need a cloud platform I'll definitely use GCP. But I think that kind of mutualism is actually better in practice than altruism.
