A study by Sabrina Haque and Christoph Csallner sifted 2,652 candidate bug reports down to 600 validated accessibility issues across Claude Code, GitHub Copilot in VS Code, the Cursor community forum, OpenAI Codex and OpenCode. Maintainers engaged with 66.4% of Copilot’s issues but only 2.8% of Codex’s, while bots auto-closed 73.8% of Claude Code’s reports and 43.9% of OpenCode’s — and tickets a bot closed took three to four times longer to resolve than tickets a person touched.
The hosts also take seriously what the study can’t show: bug trackers measure reporting and maintenance culture, not lived outcomes, and Microsoft’s own research on blind and low-vision developers found real efficiency gains alongside new friction. A Cursor user whose own accessibility report sat unanswered still called the tool more usable than its rivals — proof that maintenance gaps and net benefit can coexist in the same tool.
