It’s not a paid for feature, but it’s a project that is part of their monetization (ads, data etc) and continued engagement. Put another way, it’s a value add for something that makes them money and not educational in nature either. Otherwise one could use any IP for advertising their non-paid for products. Which for Meta is everything.
