Yes the reason I asked if you are familiar with Facebook pages is because this has to do with ads.
The actual Facebook announcement has a better explanation.
https://newsroom.fb.com/news/2017/08/bl ... alse-news/Facebook pages are not necessarily commercial pages. But one major difference is that one must be an actual Facebook user to administrate them, and also, Facebook pages allows one to create ads.
The thing to understand about Facebook pages and ad creation is that you can get incredibly specific and granular with whom you want to target. I administer three Facebook pages, none of which are "commercial" per se. This is what FB is cracking down on, and it's part of a larger effort that started back a couple years ago, and was ramped up earlier this year.
Something you might not also be aware of is the Trending stories. Trending stories give page admins an idea what the people in one's network(s) are talking about, engaging with, and clicking on. At one point during election season, Facebook took away the snippets under the trending link, leaving only the link. They put it back, probably because the negative click-bait effect taking away the snippet likely created. These small details make huge differences, especially for Facebook page admins that create a lot of Facebook ads or rely on them as part of their business model. Again, my organizations are not in that boat, though one will do them every once in a blue moon to publicize something.
In recent months, Facebook has also ramped up their staffing around handling content complaints. Everybody still complains about it because in fact, it's the overt censorship department.
I think it will work because over the past 5 years of doing this, I've seen these announced algorithms, however vague the announcement, work to affect the reach and engagement of pages.
