That’s one perspective and while I understand it it’s not one I’ve agreed with. An alternate view is that it forces all parts of your tech stack to be open sourced even things that have nothing to do with, or at most ancillary relation to the relevant service. OSS software is valuable but AGPL steps (in my view anyway) waaaay outside of what’s reasonable to try to prevent servicifying OSS. I think most companies would be fine with a GPL-like license that forced you to share the source for that code even if it’s behind a service. The viral nature of AGPL makes it toxic to almost everyone unless you’re willing to pay the copyright holders for special permission. That’s certainly fine but to me it’s less OSS and more like a viral source available license.

Alternative point of view: opensource isn't the same as freeloading
