The legality of circumventing geo-blocking to access foreign video services under local copyright laws is unclear and varies by country.[14] Members of the entertainment industry (including broadcasters and studios) have contended that the use of VPNs and similar services to evade geo-blocking by online video services is a violation of copyright laws, as the foreign service does not hold the rights to make their content available in the user's country—thus infringing and undermining the rights held by a local rightsholder.[2][3][15] Accessing online video services from outside the country in which they operate is typically considered a violation of their respective terms of use; some services have implemented measures to block VPN users, despite there being legitimate uses for such proxy services, under the assumption that they are using them to evade geographic filtering.[6][13][16][6][7][17]
