I share your sentiment and would love to expand how I feel as if even AGPL isn't enough for cloud providers like Amazon, Google etc. which can just technically run it on their servers without too much modifications or release the modifications and still compete against the original AGPL party

Personally I get worried that even AGPL might not be enough for me if I create a service which faces the public because if it gets large enough then companies technically can still call dibs on me and use their infrastructure to compete against me and I could do nothing...

It was an interesting thought experiment and made me blur the lines between (Fully open source good, source available bad) to well... it depends. And I think everyone should have such nuance since I don't think we live in a world of black and white but its interesting to hear everyone's opinion on it as this topic gets raised every once in a while.
