OK, the internet freedom already ended last time in Turkey with its own TPP-like bill that already passed recently. Revival of the freedom in Turkey is not going to be an easy thing anyway but there are already workarounds to the cyber-censorship like that as if even the non-Turkish people can use them. So the non-Turkish people who are going to use those tools for privacy protection are likely to be Americans, Europeans and people in some parts of Asia whose privacy is invaded.
Tor is one of these tools for privacy protections but the downsides are that some of the addons do too much in privacy protections as if they block most of the functional contents on the popular websites you want to browse with that web browser and the tool is being used by bad guys in addition to good guys. It may be a problem trying to capture bad guys like that when Tor is like protecting everyone. Not to mention that the users in Turkey are already using it to access Twitter as it was recently banned in a reasonless way but even then, it is one of the services affected by the spying agencies that their users in the western regions have been spied. The workaround for Turkey users using Twitter is with the SMS assigned by Twitter but the safest way will be to use the SMS software provided by third-party company on Cyangenmod for various Android devices that support that custom OS. Another workaround will be to use Google DNS but forget about it as Google services are also affected by those spying agencies as well.
Next is OkayFreedomVPN which is the VPN service I've never seen before until today. You can get the free one which is up to 1GB which may be a problem if you're not using paid subscription. It should be useful for users around the globe perhaps for privacy protection purposes.
We don't know what is the true fucking reason for banning Twitter like that but back in 2010, Youtube was banned in Turkey due to some offensive materials which might be the acceptable reason or something but back then, that was some kind of news we never cared about.
