I disagree - to me, it _is_ a huge deal. It's an overstep of a boundary that definitely should not have been crossed.
Yoast has always been borderline spammy with their upgrade nags, but at least historically they followed the WordPress guidelines and kept them inside of the Yoast pages. But flat-out injecting ads into every admin page with not much context is a step too far in my opinion.
As far as I'm concerned, automattic should revoke their wordpress.org plugin hosting until this has been addressed (as this clearly violates their hosting guidelines) and a public apology is issued.
It has been addressed and their CEO offered hundreds of apologies on Twitter. It is definitely not okay and I would still not use them as there are better plugins out there, but they (now) say they made a mistake and owned it.
The SEO framework (slug: autodescription) is great and performs about 30x as good as Yoast SEO in terms of processing time. They’re also pretty strict about sticking to WordPress’ native styles.

Unfortunately Automattic only contributes to WordPress.org [0]. Automattic actually owns WordPress.com [1] which is a separate-ish entity, and does not have any authority over plugins hosted on WordPress.org.
