I am 110% in favor of breaking the two party stranglehold. It's long overdue. It needs to end yesterday.
But hot fuck, this is LITERALLY THE WORST POSSIBLE TIME to vote third party. I read here and on Reddit that people are promising to vote third party because Biden hasn't personally solved the middle east conflict or whatever, but doing that in the presidential election amounts to screaming "fuck yeah I love Trump and everything he stands for".
Vote Biden or vote Trump. There is no third choice. Doing literally anything else is a vote for Trump.
Make sure you're also blocking all other outbound DNS at your firewall. Many "smart" devices (and presumably some apps, though I have no way to check this) are hard coded to use 8.8.8.8 regardless of what DCHP says to use.
