overoxygenate

to kill with excessive supply of something that sustains

Example #1: Clickbaity titles overoxygenated these magazines and they lost their audience in a week
Example #2: "Weston's assertion that "photography has opened the blinds to a new world vision" seems typical of the overoxygenated hopes of modernism in all the arts during the first third of the century - hopes since abandoned". (Susan Sontag "On Photography", 1971)
