What are well-known cases where a much cheaper software product successfully took customers from an expensive incumbent by cloning its core features — and what specifically made the switch possible for those customers?
Ten documented challenger-versus-incumbent cases, selected from a broader live-web scan — from Linux versus proprietary Unix through Zoom versus Webex to Aurora versus Oracle. Each row carries evidence of displacement, the price or TCO gap, the cloned core job, the exact switch enabler, and what refused to port; cases are backed by 2 to 72 independent supporting hosts each. In every case price opened the door, but the decisive variable was lowering total switching cost.
Each row is one case. A filled cell means the sources document that bridge mechanism for the case; hover or tap a cell for the exact mechanism, and the row name for evidence, cost gap and what stayed behind. Width of the right bar shows independent supporting hosts.
Evidence it won, the cost gap, and the boundary where customers stayed with the incumbent — cloning was necessary, never sufficient, and parity was never total.
| Case | Cloned core job | Exact switch mechanism | What did not port | Hosts | Source |

Method: 10 challenger/incumbent case rows from a live-web scan, one row per normalized pair; each row carries one representative source URL (10 distinct hosts, no URL reused) plus counts of supporting pages and independent hosts (2–72 hosts, 2–84 pages per case). "Hosts" measures independent corroborating websites, not customers. Quoted prices are historical or list prices and move over time; the switching mechanism matters more than today's price. Long evidence text is trimmed in cards for space; full detail sits in the sources.
