Yahoo: stop reading and commenting on emails from vendors
Since the "New Mail" version of Yahoo Mail was forced on me, when I open advertising emails from vendors I've done business with, Yahoo now comments on the sales being offered in the email.
This is totally inappropriate. Yahoo should not be reading my emails, and least of all commenting on them! I do not consent to Yahoo engaging with my email messages!
Stop reading and commenting on my emails!

We’d like to look more into this, please send us a DM on Twitter at @YahooCare, containing your Yahoo ID and a screenshot of your experience.

It's not a reasonable expectation that I respond to Yahoo's offer to look into this problem on Twitter. I can respond by email, or through another Yahoo link, but I don't use Twitter, Facebook, or any other social media. Yahoo shouldn't require the use of an online platform other than its own to communicate with users. This is just getting more and more bizarre!
