While USAID had to create a Twitter clone for its purpose in Cuba it does not have to do so in other countries. There Twitter is already established and can be readily (ab-)used by foreign governments just like USAID had planned for its Cuba clone. Blocking Twitter, as Turkey has recently done, may be at times necessary to prevent U.S. sponsored "regime change" endeavors.
This is the ultimate result of these misguided efforts. The US builds mistrust and provides justification for suppression of democratic channels when they poison the waters of existing ones.
