Bitcoin cannot be controlled by governments, we agree on that, but... They can ban it (and cryptocurrencies in general), put restrictions, and what is worse, know who uses it. And for me the latter is the worst, we use our smartphones to send or receive, our computers with our IP, our credit cards and bank accounts to buy, and we always leave a trace even if we don't want to. They can't control Bitcoin, but unfortunately they can control who uses it.
