This is indeed good news. There is one company that should also be pressured: Whole Foods.
Amazon just bought Whole Foods and needs Whole Foods to prosper. Amazon streams the National Rifle Association channel, which is basically a barrage of hate speech against everyone who does not support their agenda. Boycotting or otherwise pressuring Whole Foods to tell Jeff Bezos to drop the NRA Channel is one way this tempeh-loving town can mess with the NRA. Otherwise, Amazon is just too big to boycott. Whole Foods is Jeff Bezo's one soft target.

Apple also streams National Rifle Association hate speech. One small thing you can do is contact Apple support and talk to a case manager. My case manager was nice. I politely explained that I was calling to urge Apple to drop the NRA channel. Right now, the tech giants are not joining Alamo and Delta in disassociating from the NRA. It's time to remind them that consumers want to buy from companies that don't stream hate speech.
There is an Apple Support site that's easy to find. Take 5 minutes and express yourself. Then take the survey about your experience- you will have an opportunity to communicate your position.

Great start! Now, who's going to boycott the military industrial complex by refusing to pay income taxes?

FedEx is a stretch - their founder is a nutbag conservative.

I would say the major difference between all these other companies and Amazon/Apple are that the other companies had business affiliations that offered discounts to NRA members (and thus presumably a kickback arrangement that gave money to the NRA when their members used those companies' services). Apple and Amazon, in this context, are mostly just media platforms. I'd be happy if they dropped the NRA content channels, but it likely represents significantly less revenue than the member discount schemes.
