The 5 main issues with Cloudflare

Privacy Concerns - User data is likely to be stored and used against users' best interest.

Cloudflare has experienced major data leaks (e.g., the 2017 "Cloudbleed" bug) and its services have been exploited to expose sensitive user data, including passwords, cookies and authentication tokens. Its CDN caching behavior has also been exploited to infer user locations.Sources:TechCrunch: Major Cloudflare bug leaked sensitive data from customers’ websites (2017)The Register: CDNs: Great for speeding up the internet, bad for location privacy (2025)

Exploitative Labour Practices - Poor working conditions and low wages for workers involved in production or services.

Cloudflare has faced criticism for its labour practices, including mass layoffs (e.g., firing 1,100 staff in 2026) and poor handling of employee dismissals, with reports of HR being unable to explain reasons for terminations.Source:The Register: Cloudflare defends firing of staffer for reasons HR could not explain (2024)The Register: Cloudflare to fire 1,100 staff whose jobs just aren’t AI enough (2026)

Monopoly - Market dominance that stifles competition and limits user choice.

Cloudflare holds a significant share of the CDN market (around 20% of global web traffic) and its dominance, combined with its integration with Big Tech partners, raises concerns about market concentration and potential anti-competitive effects.Source:ZDNET: Cloudflare stutters and the internet stumbles (2019)

Reliance on Big Tech - Services relying on Big Tech for their infrastructure.

Cloudflare relies heavily on partnerships and interoperability with Big Tech firms (Google, Microsoft, Amazon) for peering, data transfer and infrastructure support. Its ecosystem is deeply intertwined with Big Tech’s.Source:TechCrunch: Google Partners With CloudFlare, Fastly, Level 3 And Highwinds To Help Developers Push Google Cloud Content To Users Faster (2015)

AI Bloat - Service has unnecessary or harmful AI features.

Cloudflare has introduced AI-driven features (e.g., bot management, AI crawler blocking) that increase computational and energy demands. Its recent pivot to AI has also led to layoffs of staff.The Register: Cloudflare to fire 1,100 staff whose jobs just aren’t AI enough (2026)
