There are a few reasons why Germany bans RT but not France24 or Voice of America. One reason is that RT is state-owned by the Russian government, while France24 and Voice of America are funded by the French and American governments, respectively. Another reason is that RT has been known to spread disinformation and propaganda, while France24 and Voice of America are more reputable news sources. Finally, RT has been accused of interfering in elections and other domestic affairs in other countries, which could be another reason why it's banned in Germany.
