Wikipedia founder Doctor Larry Sanger has called for a 48 hour social media strike.
The co-founder of the online encyclopaedia has urged people to stop using social media sites like Twitter and Facebook for two days this week in an effort to pressure the networks into restoring control of personal data to users.
In a blog post, Larry said the strike - which is set to take place from Thursday (04.07.19) to Friday (05.07.19) - would show the "massive demand" for change, as well as proving users have a "serious grievance" against the services.
He wrote: "We're going to make a lot of noise. We're going to flex our collective muscles and demand that giant, manipulative corporations give us back control over our data, privacy, and user experience."
As well as making changes to data privacy, Larry also hopes the networks become more open and interlinked, so that a post made on one service can show up on others.
He added: "This is how social media should have been developed from the beginning, rather than walled off in separate, competing networks."
The Declaration calls for social networks to be decentralised and turned into systems that respect the rights of free speech, privacy and security, and has already circulated widely on Reddit, Twitter and several other networks.
However, some users have questioned the impact of the proposed strike.
One commenter said: "I feel that even if everybody who cared went on strike, the difference in daily visitors would probably be in the error margin.
"I think most people who really care have already left the centralised social media or scaled it down to the point that a non-strike day is an exception."
