AGCOM opened proceedings over inadequate transparency in information supplied for transferring a fixed line to a new address: the process required termination, could cause customers to lose offers guaranteed 'forever' and incur disconnection fees.

Appearing as a co-founder and shareholder of Mediawan, Niel accused rapporteur Charles Alloncle of spreading 'approximations', 'fake news' and 'lies', and said the committee had become a 'circus', adding that he was 'not a clown'. Asked about possible privatisation of public broadcasting, he said he wanted public service broadcasting to continue but would consider buying the channels if they were put up for sale.

Nice-Matin Group, owned by Xavier Niel, acquired Chouet'Press, which owns the celebrity photography agency Bestimage founded by Michèle 'Mimi' Marchand, in June 2024. In 2026, Mediapart reported that Niel had injected €3.7 million to support the structurally loss-making company, renewing questions about his interest in a paparazzi agency.

After Paris Match published surreptitiously taken photographs showing MP Charles Alloncle with a colleague, Mediapart established that Niel had circulated the images before publication. Alloncle, who had clashed sharply with Niel during an April parliamentary hearing, subsequently accused the billionaire of organising, financing and circulating material from a 'hunt' and denounced 'mafia methods'.
