AGPL throws the community baby out with the bathwater.
It's working OK, but honestly that may be because 1) most people don't care about licensing, even the difference between public domain, AGPL, BSD, or GPL, or frankly shareware, or even pirated; and 2) they're running from twitter so they have to go somewhere.
It may have been bit much to say "baby with bathwater", but to fix the analogy maybe I can say "Throw the baby out with the bathwater, but it's fine because you have another baby, and half as many babies ain't too bad. At least it's not zero.".
Yes. Because the way it which it mandates upstreaming means that it creates a huge liability and unclear exactly what is in scope of the mandated contributing.
E.g. real lawyers looking at it have said that if you build a web app, and it uses mongodb (AGPL) to store some state, then you may need to opensource your web app.
It's not even clear if the AGPL software needs to be in the serving path. Maybe your billing pipeline uses mongodb, and now you have to opensource your frontend?
The counter argument from AGPL proponents I've seen is almost always "Good. They should need to opensource everything on their servers. I should be able to spin up exactly what they run, on my own servers".
Even a narrower interpretation that only in-scopes your patch to make mongodb work with your in-house SSO means you need to opensource things that you don't necessarily even own.
Again, the answer from proponents is "Good, all in-house SSO should die".
Edit: although, I disagree AGPL is problematic, see my other comment.

AGPL is not LGPL, so is the client library of a client/server thing enough to infect you? Probably.
If there is no client library, what's the license on the example code that you used in your app?
The issue here is liability and what the lawyers counseling a company will recommend. If your design contain IP that the company has valued (very common), risking leakage of that IP by using a library that in legalese seems to suggest that you may have to release your design, you can probably bet that the lawyers will recommend to find another technical solution. Protecting business value and avoid exposure, liability drives conservatism. And in my experience will always triumph over technology choice. Esp if there seems to be a possible choice to be made. Including developing your own solution.
As an open source HW creator I have to decide if I develop stuff for my own amusement, or if I do it to (in somehow small way) help the world - which means other using my creations. And then consider if the license I use support that goal. Since I don't just develop stuff for my own amusement I've decided to use a permissive license since I think that makes it easiest for others to use my stuff.
Judging by the number of downloads, messages and additional work I've gotten, it seems to work out pretty ok.
IMO it's normal and expected that companies hate GPL(v2 or v3 or AGPL). It's not okay but also okay to steal GPL code too, it's just an introductory price phase for inescapable lock-in which even Google hasn't been able to get away from.
Releasing under AGPL is a great way to not see your design being used and contributed to. At least by entities that wants to abide by the license and do the right thing. Entities that steal work done by others, have no intention to contribute back may do differently.
