First off, we are nowhere near "shutting down social web". WhatsApp was shutdown by a court order because they did not comply with a subpoena to hand over information from a user in July and August. I recently submitted a link with a local (Brazilian) newspaper explaining the issue.
>If Brazil’s conservative Congress gets its way, they’re going to take down the entire social web as we know it, with bills circulating through the legislature to criminalize posting social media content and to allow the government to spy on its citizens.
Conservatives are not the only ones trying to censor the internet in here, absolutely every politician wants it.
>It’s an about-face from last year, when President Dilma Rousseff approved Marco Civil, a groundbreaking Internet “Bill of Rights”, as a response to the Snowden revelations that the NSA was spying on Brazil. The landmark bill, Brazil’s first internet legislation, protects net neutrality, user privacy and freedom of speech.
On the contrary! Marco Civil threatens user privacy (more below), and the "net neutrality" part has lead to just the same that happened today: Mobile companies were forced to shutdown their "free WhatsApp and Facebook" plans, making millions get blocked from WhatsApp[4]. Anyway, back to the privacy issues, article 11 of the text[1] is the more worrying one. Some highlights:
§ 2º A autoridade policial ou administrativa poderá requerer cautelarmente que os registros de conexão sejam guardados por prazo superior ao previsto no caput. § 4º O provedor responsável pela guarda dos registros deverá manter sigilo em relação ao requerimento previsto no § 2º
It says basically that police can require records of visited CONTENT without a court order and the ISP is required to supply that without informing the user. Somewhere else in the text it forces ISPs to store user history for a year. If the text really wanted to protect user privacy it would say something about cryptography, which isn't mentioned anywhere in the text.
Article 2 says there must be a "social purpose" for websites and that gov. may take websites down if it feels it doesn't serve the public interest. Brazilian govt. already has a history of censoring YouTube and Facebook videos involving politicians, judges or celebrities[5][2][3].
