In FCC filings, opposing parties argue that blocking Wi-Fi access is not only illegal but it is also against public interest. They clarified that network providers should retain the right to control their networks, but they should not be able to intentionally jam or interfere with other networks, such as the mobile hot spots that Marriott blocked at a 2013 conference in the Opryland hotel in Nashville. In their complaint to the FCC, Microsoft states:
While the technology behind Wi-Fi de-authentication can be used for legitimate purposes, a willful use of that technology to ‘jam’ or otherwise interfere with Part 15 devices violates [existing laws].
