Bare facts have no protection. Netflix owns Squid Game's media content, but they have no ownership over "Netflix has a program called Squid Game that is currently available." or "As of blahblah date Netflix will no longer have Squid Game available in CountryX."
But that's just the pessimist in me complaining about bigCo.
Sites exist like "CanIStreamIt?" for years and haven't been shut down by Netflix/Amazon, so maybe there's a legal way to go about it?
