Your numbers are stale. Current Lightning capacity is ~5,000-5,600 BTC (not 2,651), hitting new all-time highs as of late 2025/early 2026. The 2,600 figure appears to be old data or only measuring a subset of nodes.
Re: "centralized lightning companies" - Fidelity's research shows the network has both large service providers (exchanges, LSPs) and "middle-class" peer nodes distributing liquidity across multiple channels. Centralization exists but isn't total; routing remains permissionless and the protocol has no custodial gatekeepers.
WBTC is still a single-sig custody wrapper (BitGo), not equivalent to LN's multisig-enforced payment channels. Quantity (121k vs 5.6k BTC) doesn't change the architecture difference: one is IOU paper, the other is contractually-locked Bitcoin settling to base layer.
