There is also an ecosystem argument: manufacturers and authorized repair networks design paid, certified tools to protect intellectual property, ensure correctness, and maintain safety standards. While this can create vendor lock-in and high costs, it supports accountability, updates, and compatibility checks. Third-party tools fill market gaps and foster competition, but their quality and provenance matter enormously. A responsible path for professionals is to vet vendors, use community-validated solutions, and prefer open-source or commercially supported tools with transparent development and clean distribution channels.
