Mozilla Foundation

Industry Open Source

A nonprofit and taxable-subsidiary ecosystem behind Firefox and open-web work, still useful as a public-interest browser alternative but weakened by search/ad revenue dependence, centralized governance, product bloat, sponsored surfaces, and trust failures. Mozilla Foundation remains weak because of person-dependent governance, material opacity, and surveillance capture, even where the product or service has practical value.

Why this matters: Mozilla is a crucial calibration case: nonprofit branding and open-web values deserve credit, but a public-interest browser can still become bureaucratic, revenue-dependent, and paternalistic toward users.
