Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ESLint

Slow performance on large codebases compared to newer tools like Oxlint and Biome
Complexity in configuration from scratch, particularly for TypeScript support
Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features

OneTrust

Complex usage-based pricing model with multiple meters (admin users, inventory size, daily visitors, data subjects) making total cost unpredictable
No published pricing examples or per-unit costs; all pricing requires custom quotes
Each solution area uses different pricing metrics, requiring complex calculations for multi-solution purchases
Enterprise-only positioning (Fortune 500 focus) suggests premium pricing, discouraging mid-market or startup adoption
Platform complexity and multiple solution areas may result in significant implementation and ongoing costs not disclosed upfront
