If the Buddha praised Samatha, why is it losing importance?

It seems like these days, teachers are looking down to Samatha meditation, I would like to understand why, based on the suttas, this the meditation praised by the Buddha. Could someone explain why Vipassana is so much more present in Theravada tradition, eventhough the Buddha practiced a lot of Samatha? I'm sure there are good reasons. " And what kind of meditation did the Blessed One praise? Here, brahmin, quite secluded from sensual pleasures, secluded from unwholesome states, a bhikkhu enters upon and abides in the first jhana … With the stilling of applied and sustained thought, he bhikkhu enters upon and abides in the second jhana … With the fading away as well of rapture … he bhikkhu enters upon and abides in the third jhana … With the abandoning of pleasure and pain … he bhikkhu enters upon and abides in the fourth jhana … The Blessed One praised that kind of meditation." Majjhima Nikaya 108.27
