Being a single player who plays during all hours of the day on a daily basis since launch, I'd have expected to get at least 2 at some point if it were true. Today, I collected my first message bottle right when it hit 5 a.m. I will see if there's an additional one in the evening.
Unless I see concrete proof of this other than hearsay (because I know the bottles can easily be missed if someone doesn't scour the beach much while playing), I'll stick with with 1 bottle for single on one's own Island theory - not counting the Nook Miles Islands as I know you can easily get additional recipes there.
