How has Hiko been here for so long

Stg he’s been the weakest link of this team since stage 1 last year yet they are so keen on keeping him

Hiko brings in a lot of profit for 100T i guess.

because he has a big stream following and 100T is a content org first and foremost is my guess. They might make changes if Stage 1 doesn't pan out with good results but it is unlikely (as it may just be the new squad synergy troubles as well)
