This comes down to arguing over semantics. Many will argue that "open source" means using a license listed at https://opensource.org/licenses/ https://opensource.org/licenses/ . Even CC0 isn't considered open source by this standard. Even I feel that "700M monthly active user" gives not-so-open vibes, but frankly many of these "open source" licenses have oddly restrictive requirements as well.
