(keep in mind that i am just overanalyzing, but this still can be true)
I was watching kennyS stream the past few days, and he seemed a lot happier than he was before he was benched, granted, I dont actually know, but he does look a lot happier. But there was a few things that he said that I found a bit worrying. He said if he was ever called back from the bench the way jackz did, he would not want to go back, and "it is not what both parts want", which I thought was strange because it always seemed like he and the rest of the team were good friends, and its strange that all of the sudden he doesn't want to play with that team anymore.
First of all the move seems VERY rushed, bringing jackz back in and moving NiKo to hybrid player, I highly doubt it was something that was well planned, it seems like a very recent decision, and since nexa said on HLTV confirmed that they wanted to make the team with NiKo and kennys work, and it will take multiple months, it would not make any sense for him to bench kenny almost right after, replace him with JaCkz and move NiKo to awp/rifle hybrid. I also feel like kenny might have requested to be benched, or at least pressured G2 into benching him, due to internal problems.
Internal issues isnt far fetched at all either, the entire team always looked dead and very miserable when they show up on camera during games, and malek seem to be more and more frustrated with the team at all, and I dont think kenny would like to play in this kind of team environment. I dont think JaCkz being benched a few months ago helps either.
It seems like hes unhappy with his roles on the team (being a support player rather than a star player), and he made multiple remarks on stream about it. One example is inn one of his faceit games he asked his teammate if he should smoke con for him, and that teammate said something along the lines of "kennys support player", and kenny responded with "unfortunately I am stuck with it"
Also regarding if NiKo had any say in benching him, he said that he does not care. He said hes very burnt out which is to be expected, and that he wants to look for new opportunities.
I personally hope that kenny would find a new team that has a structure where he can shine and be a star player rather than a support player with little freedom like the way he is on G2, I am sure that is what he wants too. I would not want kenny to go play in G2 again, at least not with this core. He has been statistically the best support player for the past few months, but he just should not be utilized that way.
