I'm already using the Shadowsocks bridge in Mullvad. If things get more serious, I'll do some research and consider switching to Tor with either obfs4 or WebTunnel on Tails, and Snowflake on mobile.
Yes, this way they need 2 seconds more to track you, if they want. TOR is the most monitored Network by all security agencies and secret services, it was created by these. I2P is maybe somewhat more secure. Decentralized network is anyway the future, also P2P communications.
I2P certainly is not the clearnet, but if they continue to contaminate the clearnet with massive surveillance, there are not much more alternatives if you don't want to go back to communicate with Finger commands like in the 70th (still works, see also this)
