If the restrict act passes the government can ban any technology they want.
If you access banned technology you will face up to a million dollar fine and 20 years imprisonment.
The RESTRICT Act is not limited to just TikTok. It gives the government authority over all forms of communication domestic or abroad and grants powers to “enforce any mitigation measure to address any risk” to national security now and in any “potential future transaction”
This includes the possibility of banning Tor/ I2P / VPN or even foreign CHAN sites in the name of "National security" under threat of fine/imprisonment for anyone caught using them.
