BP (still haven’t forgiven them for lubricating the Gulf of Mexico and being like “oops, sorry”)
Verizon (injecting tracking IDs into customer web traffic to sell to advertisers while also charging me $60/mo for 2 GB of data – I’m a product or a customer. I will not be both.)
AT&T (After so many years, I forget exactly why, but they’re just evil)
The entire states of Florida and Texas
The lottery (I’d have the same payout and more fun just setting the money on fire)
Microsoft (It’s MY computer, not yours)
Apple (Overpriced hardware, control-freak walled garden, everything needs a damn $29 dongle, etc)
Reddit, Facebook, Twitter (also blocked in firewall)
Amazon (except the 2-3 times a year they give me a free month of Prime and I buy all my stuff, take the free 1-2 day shipping and cancel before they bill me)
