"The F-Droid project cannot require that developers register their apps through Google, but at the same time, we cannot 'take over' the application identifiers for the open-source apps we distribute, as that would effectively seize exclusive distribution rights to those applications," he said. "If it were to be put into effect, the developer registration decree will end the F-Droid project and other free/open source app distribution sources as we know them today," said Prud'hommeaux.
