You can't build a hip start up around it and get millions of VC money. Because of the APGL you'd have to open source your service. Something the typical unicorn startup isn't too keen on. Taking community software: yes. Building a for profit product around it: yes. Giving back to the community: lol no.

Yeah, I personally dislike AGPL but even I do not see any practical issues with it for this use.

I agree, for me for this kind of thing it isn't a deal breaker. But for many people it may be.

However, I will say that combined with the freemium model it does give me pause. The reason is I will likely want to add some features that will conflict with the premium version. That means that my changes have near zero chance of getting incorporated into the community version and I'll have to maintain a public fork.
