The claim does not mention that Anthropic was actively negotiating with the EU about granting access, which was announced just 13 days after the session on 1 June 2026.
The number of partner companies grew from approximately 12 launch partners to roughly 50 by April 2026, and further expansion was planned — making 'a few' somewhat imprecise.
The restricted-access programme is formally called 'Project Glasswing', which the MEP did not reference.
The Linux Foundation, a globally-scoped non-profit, was among the launch partners alongside US-headquartered companies.
