Where can this rule be found? That seems like a really odd rule, and https://www.facebook.com/business/help/388369961318508?id=12... says the opposite:
"Avoid too much text on the image itself. We've found that images with less than 20% text perform better, though there is no limit on the amount of text that can exist in your ad image."
With a screenshot of text, it's super easy to understand how our tech works and whether it is useful for a particular person. But FB wouldn't let us boost posts that had images of our product in use.
I'd be curious to hear from others how much FB penalizes advertisers in terms of cost/reach if they have lots of text.
But still their algo doesn't promote heavy text as much. It's a black box; ads aren't as simple as highest bidder, FB takes engagement on a per user basis into account and evidently heavy text lowers.
Which is ironic given they added those text only posts & the takeover of Memes which at least for me drove my personal browsing to IG only. And now that's starting to go the same way. maybe meme-ification is humanly inherent lol. I'm starting to unfollow friends who only post those inspirational memes and crap. I just want photos, inspiring content from creators/athletes that are relevant to me, and family updates.

They later converted text in ads into a penalty, so you pay more (as an advertiser) for it.
The recommended amount of text on the image is less than 20%. Their system also doesn't like text because of potential "circumventions of policy" with putting text in images. Weird fonts that are not machine-readable will likely get the account banned fast.
