I have just been moved, involuntarily, to Netflix's ad tier

So I just received an e-mail from Netflix saying the following:
(it's actually a four-line e-mail that says almost nothing but expands to this when I copy it. How do they do that?)
Hi cmplxgal,
We hope you're enjoying everything Netflix has to offer, and we want to make sure you know about some changes ahead.
What you need to know:
Your Basic plan is being discontinued, and your new $6.99 Standard with ads plan automatically begins on your next billing date, September 6.
Your new plan includes:
• Lower price: Save 40% each month.
Better video quality: Stream in Full HD (1080p).
• More devices: Watch and download on 2 household devices at the same time.
• A few short ads: Designed to not interrupt you during a scene — and no ads on Kids profiles.
There's nothing you need to do to keep enjoying Netflix. If you'd like to change your plan to Standard ($15.49/month) or Premium ($22.99/month), you can update your plan anytime. Upgrading to Standard or Premium may change your billing date.
We're here to help if you need it. You can always manage your membership by visiting your Account. Visit the Help Center for more info or contact us.

------------------------
I have been debating whether to cancel my Netflix subscription, as I haven't watched anything there for a while, and this makes for an easy decision. I knew this was coming, as Netflix announced its intentions a while ago. I refuse to watch ads, so I will cancel now and come back for a month if there's something I particularly want to watch. There are several shows that I wished would release new seasons, but none of them ever did.
