"absence of any credible system of accountability for the police" as one major reason for why the protests became more radical. Local media coverage The protests received significant press attention. Nathan Ruser from ASPI identified the protests as the most live-streamed social unrest in history. According to a poll conducted by CUHK, live feeds have replaced traditional media, social media and Telegram as the main way for citizens of Hong Kong to access protest-related information. Ruser suggested that unlike other protests, the widespread use of livestreaming technology in the Hong Kong protests meant that there was "almost parity when it comes to what [one] can learn remotely researching it to actually being there". Many of Hong Kong's media outlets are owned by local tycoons who have significant business ties in the mainland, so many of them adopt self-censorship at some level and have mostly maintained a conservative editorial line in their coverage of the protests.

Protesters also placed political pressure on various corporations, urging them to stop placing advertisements on TVB. On the other hand, Radio Television Hong Kong (RTHK), a public broadcasting service, faced criticisms of bias in favour of the protest movement. Its critics have surrounded the headquarters of RTHK and assaulted its reporters.

The police were criticised by journalists and democrats for interfering with press freedom. In response to around 200 complaints received by the Communications Authority, RTHK apologised "to any police officers or others
