More possibly a move to dip into the revenue stream of "influencer marketing". There are a plethora of companies with "influencer marketing platforms" that scrape Instagram likes and followers
of influencers and intermediate between advertisers and them. This basically seems to deny "non-official" platforms data
I can see this being a motivation as well, not unlike how over time FB and twitter closed off parts of their api so they could monetize it for themselves. Though I think this will create new opportunities for NLP services to expand to cover the ground like scraping companies will no longer be able to cover.
