Uh, the highest-funded terrestrial telescope project of the last 10 years has been the Rubin Observatory, which is intended to detect more interstellar objects (along with two other large goals - variability studies and galactic rotation curve studies to understand dark energy). The effort spent arguing about Oumuamua is a tiny, microscopic fraction of grant money in astronomy. (I work on software to detect interstellar objects)
