It's not true. I don't particularly like RMS, I don't agree with his views about free software and I don't like GPL as a license. I also think his views on many political issues are naive, go against human nature and if implemented would cause a lot of harm.
Still, I think the way he was forced to go is shameful. Some journalists couldn't interpret a simple statement (sadly very common), started an outrage and the pressure became too much. I hope he sues them and wins enough money to have a peaceful retirement. I don't want a world where some of the biggest contributors to technological wealth we have access to can't freely state their views, qualms and doubts or even start a discussion about controversial moral issues.
