The L0 public licenses come with grace periods, essentially free trials. Right now they're at 90 days, but will almost certainly shorten, perhaps to 30 days or less.
The utility of L0 is to make it possible to offer one set of public tools with, say, a noncommercial use limitation, but offer those who need to use commercially an easy way to buy the right to do that. "License Zero", as in near-zero friction.
Zero is impossible of course, because there will always be some friction in the additional step of getting a different license, versus not needing a separately license at all. But it's up to developers to decide what's best, in terms of optimizing leverage to command support, on the hand, and minimizing friction that puts a brake on adoption, on the other. Purely proprietary software with closed source is at one extreme. Hyper permissive licenses like 0BSD are on the other.
My point is that "commercial" versus "noncommercial" isn't the same distinction you want to use for "pay us" versus "don't pay us". The proper price point for many commercial uses of software products is still zero.
Agreed. Some may opt for the reciprocal public license for that reason, since it allows unmodified use for commercial purposes.
Leaving the terms behind for a moment, to focus on context: Many users, both individual and business, don't have any money to sue for. They're judgment proof. But if they make it to cash flow, they should pay. They'll almost certainly have paid for other goods and services, like AWS or SaaS, before then.
