Unpopular Druids - Why?

In a DnD Shorts video today I heard that in a survey of a couple of years ago, the Druid was by far the least picked class in the game (at that time at least). As Druid is undoubtedly my absolute favourite class, especially due to the amazing flavour of the various subclasses (I mean, Spores Druids, master of fungi, come on), combined with being a fullcaster with good spells (guidance, thorn whip, goodberry, absorb elements, moonbeam, spike growth, call lightning, revivify), amazing summoning options like Conjure Animals/Woodland Beings and Giant Insect, and the unique, flavourful and powerful Wild Shape ability, I'm really wondering why relatively few people want to play one. What are your thoughts?
