It's just a saying; a platitude like "get well soon", "just be yourself", or "employees must wash hands". Safety (really security in general) is top priority only after you've already knocked out user acquisition, basic short term financial stability, and product stability. As such, by "safety is a top priority", they really mean "safety is a top priority now".
