The analogy: "It is not a chair; it is a puppy." Ongoing care is the cost.
| Model | Cost Pattern | Outcome |
|---|---|---|
| Proprietary rent | Recurring license OpEx | Lock-in risk |
| FLOSS (unfunded) | 0% upstream | Security + supply-chain risk |
| FLOSS (sustained) | 1–5% upstream | Resilience and velocity |
The 1–5% rule: Allocate a slice of contract value to upstream sustainment.
