I'm guessing most those people are just late and came in after the couple "exoduses" of sorts of people jumping ship from Ubuntu to the offshoot projects (Mint, etc.).
As far as my memory and perception of the situation go, there was a time where Ubuntu was #1 on distrowatch and couldn't conceivably be dethroned. Then, they added the spyware in '12 and snaps in '16, neither of which were by any measure without controversy, IMO. (And, spoiler alert -- they have since tumbled down from that position.)
