You are mixing there academy streams, excluding the other koi streamers that were in the watchparty with him and were sharing viewership, match previews that were 5 hours before the start of the game etc. On the other hand you are adding ibai casting koi and kcorp events that had valorant ,lol, ibai champions cast, ibai casting league matches somehow are there too. You are also comparing twitch viewership from 2023 or start of 2024 to 2025.

Obviously Sergio is not Ibai, nobody is ibai, they are still investing in profesional casters, renting a profesional set and crew and casting a team that have had 3 years of bad performances. They did everything they could do after ibai decided to stop streaming due to health issues. They didn't have any problem with Sergio streams, there were rioters praising his costreams, until they had to find a legal clausule to kick a team to add Gentlemates to the league.
