I usually see HTML emails with their logos in the corners. This remotely loaded logo is used for Paypal:

There are some advertisement e-mails from PayPal that do indeed have HTML formatting. Bad enough.
However, important e-mail, like payment confirmations, money received, etc. are plain-text. At least all that I ever get.
Also, there's a different between MIME e-mail with inline attachments, and HTML e-mail, in that HTML allows a variety of tricks, that aren't possible with MIME e-mail, such as link spoofing. e.g. "<a href="http://www.appleinsider.com.some.fraudulent.site.cn/snatchThePassword.php">http://www.appleinsider.com/</a>"

In other words, spoofing an AI mail could compromise a user's security significantly.
Sure but they'd have to go to all the trouble of recreating the AI home page, registering a domain that looked like appleinsider.com (which they could write in a plain text email) bulk send to tens of thousands of random email addresses in the hope that some of the 250 or so active users here are in the list and click the link so they can get a password, which may or may not be of any use to them.
The prevention being for AI to offer the option to get plain text emails, which requires the AI users to actually change the preference and the people who are the typical target of social engineering most likely won't change it anyway.
I don't see it being anywhere near the security risk of Paypal's HTML emails.
No, they don't have to go through that trouble, they just have to recreate the AI login page, and then after they snatch the password, redirect to the regular appleinsider site. They also don't have to register a domain that looks like appleinsider.com, because they can name a host www.appleinsider.com.t.151140.qwetsx.cn and most people won't read past the appleinsider.com part, because we have long stopped using intelligible URLs on the web, so instead of meaningful URL paths we have machine generated gobbledeegook that nobody looks at anymore if the beginning seems about OK, particularly on small screen devices, where the URL field often isn't even long enough to show more than the start of a URL.
In a low-wage country, the effort of doing such a phishing attack is minimal; it's not like they have to lick stamps to send out these e-mails to hundreds of thousands of people. It's more than profitable if out of a hundred thousand e-mail sent out, 100 are received by AI readers, and one or two of them enter the password on the wrong page. All these sort of attacks are number games. They don't cost a lot of effort, and it suffices if they strike gold every few attacks. If they phish five sites like AI, and they clean out one person's bank account as a result, it's well worth the effort for them.
Prevention would also, at least ideally, be that people have to OPT IN to HTML e-mail, not opt out of it. But at the very least should those people who are security minded and don't want to click in an unsuspecting moment at 3am after an 18h day, on the wrong link because they lapsed momentarily in attention.
The reason why phishers and spammers succeed is exactly because preventive measures are always only taken AFTER the disaster strikes, because people like you always talk down the risks.
I hope that AI at least stores the passwords to this site a tad more securely than LinkedIn did...
...because these guys obviously also thought that their site wouldn't be a security risk, or else they wouldn't have been this lax:

But if you don't believe me, simply Google: "html email security risk"
