They can still torrent the content, which is what I'm doing after I paid for the first month of Disney+ and then found out their DRM disallowed Linux because of "security levels".
Netflix also offers a subpar service on Linux for the same reason, the video resolution is limited to 720p, even with a Premium plan. The video quality can be tested on Netflix by searching for "test patterns" on the service.
The stream quality of HBO GO is consistently bad on Linux, with washed out colors.
I have no experience with Amazon Prime Video, but I've found several threads from 2019 with people complaining about the lack of 1080p streaming on Linux.
So even when Disney+ begins supporting Linux, you'll most likely get a subpar service for your money.
You'll probably never be allowed to sign up for D+ again. I'd only use charge backs as a final resort if I can't contact the company and/or I never want to do business with them in my life.
Credit chargebacks are a really great way to end up being banned from a lot of companies' businesses going forwards. It's a last resort, not a "I'm too lazy to ask for a refund" strategy.
It sounds like Disney+ was accepting refunds for preorders up until the launch day. Whether or not they can refund after presumably may depend on whether or not they can tell you've watched some of the content.
Interesting, I chargebacked a stubhub ticket I never recieved after a really terrible flow to even figure out if I got the ticket (turns out they partnered with a third party and you needed to download potentially 2!!! apps to get a scannable ticket). I didn't bother with contacting support because of how terrible the experience was. I hope they ban me.
Re: chargebacks as a last resort, yes - in my experience the credit card company will at least ask a few questions to make sure you've made a reasonable effort and have at least thought about getting some documentation of what's happened. But I'm less concerned about getting $6 back than I am about telling Disney that they lost a paying customer because they assumed I might be a pirate. It's a self-fulfilling prophecy. I never felt any desire to pirate a Netflix Original because their DRM doesn't get in my way.
I expected better, given Netflix and Amazon have been able to do it for quite some time with no problem. And I would still be willing to pay Disney's current price given their content selection if they were able to deliver it reliably on other devices, but I've been disappointed so far.
Disney are the single biggest contributor to the shitshow that is copyright law right now. I don't understand why anyone would expect them to play nice.
Personally I view is as a moral imperative to not give them any money.
