It's not necessarily just about the government. Built-in backdoors also give malicious actors more ways to access your own private information, whether to steal your identity, transfer money out of your bank account, use your credit for loans, or blackmail you. Also, other governments already use your online speech to arrest you for saying things they don't like - see China or Russia. Many EU countries are only one election away from having a government that goes in that direction already. This is only going to make it that much easier for them.
