Whether it’s Xfinity, AT&T, Verizon or some other mega corp you are using for internet access (your ISP), there are options in many parts of the country that will get you connected to the internet without sending money to conservative campaigns.
In the greater San Francisco Bay Area, I love Sonic (referral disclosure1). They are a great company with all employees actually stationed in the US, and you get to talk to a real person without having to first navigate a nonsense phone response system.
Another option in the SF Bay Area is MonkeyBrains. I think you need to have ‘line of site’ to one of their antennas (they are wireless), but I have a friend who thinks they are great.
If you have a favorite local ISP, link to it in the comments and I’ll add it here.
