Oh then it's not a surprise. On a similar note I'm seeing more mentions of Ting-Lu and Hippowdown with the phashing shenanigans
Dtail hazard chomp was also a little more popular at the start before people realized that tera fairy just makes any bulk mon clefable at home. Hippo doesnt like Bonnett or Grass Chi-Yu offensively, let alone rain as a style - It literally has almost no niche over Ting-Lu outside of maybe not being objectively weak to fairy and fighting? But even then, Vessel of Ruin and the overall stat diff makes Ting-Lu just the better choice on 85% of most teams.
