Not sure who the audience is here. If the text is in the DOM, it's gonna get indexed. Computer's don't care if text is white on a white background.
That being said, Google getting dynamically generated content (ajax) is newish (I don't think it's new enough to be "news").
More interesting is if Google can "parse" things like <noscript> or if the CSS hides content, or if text is too small and decide to rank based on that (contributing factors to a "quality" rating).
I'd guess "yeah, probably". After all, they can rank based on if your site is mobile-friendly, and that must take some interesting metrics to decide.
Google specifically fighting "black hat" SEO techniques is really, extremely old news. Google being good at indexing "all the things" - also old news.
