Twitter today announced that they are no longer giving 3rd party developers a free ride on their platform, demanding a cut of advertising revenues earned by outside 3rd party programs.
According to Duncan Riley:
The new demand follows a change to the Twitter API announced earlier that has banned all third party ad providers from auto-posting to Twitter accounts.
Twitter announced the changes in their Terms of Service (TOS) in which they state they should receive compensation:
“where Twitter content is the basis (in whole or in part) of the advertising sale .”
