So basically this episode was the representation of what’s been happening with Aqours in real life, µ’s had to start from 0 just as in the anime when no one attended their first live, Aqours didnt start from 0, because people already knew about school idols, because people are “nice”, and IRL because people already knew about Love Live so they wanted to give them a try, but there are also people that don’t want to give them the opportunity to shine (SHAINY!) because they just want to “copy” µ’s and IRL because “they are just ripoffs” and this is what Dia represents. (Dia is literally any die hard fan of  µ’s)
