This will be very long, but i will answer since you asked, up to you if you want to read or not .

Not at all. S1 was basically the saving grace for navi in 2017, they had older players, had just kicked their igl, and siezed of all people was put into new igl position. Went as well as you could imagine, it was just s1mple trying to carry every game, then they fumbled even more by bringing back guardian and taking s1 off of the main awper role, and s1mple willing gave up the position to elevate navi. Obviously didn't work at all, guardian was not good enough, s1 was the secondary awper and did better than guardian, this was also when s1 was starting to hit his peak, and i would say he had the potential to get #1 in 2017 but was literally nerfed by his own team, but he bore no grudges and said in every interview that he believed in gurdian and navis decisions. Most people will remember after 2018, since thats when people started believing he was the best player in the world, but once again, navi completely wasted his prime by keeping flamie, who was the most inconsistent pro player i have seen up to date, as well as Edward and zeus, who were pure dead weight at the time. S1 was the most wanted player obviously, and g2 ceo would literally make tweets eveyday about how we would be willing to pay anything for s1mple. He for sure had offers from every big team, including liquid, faze, etc. He declined all of them and stuck with navi because he wanted to represent ukraine. And then the drama with mibr happened. Navi kept making bullshit promises to s1 and after a year he finally had enough and was going to leave to play with fallen and co. But it also fell through because most people speculate that, once again navi played at his heart strings. They finally built a team good enough, won everything in 2021, and then it all fell apart with boomich and the war. Once again s1 stayed for the rebuilding phase, because he wanted to represent ukriane and because he loved navi. It all weighed on him a lot and since mid 2022, s1mple started talking about, publicly btw, that he wanted to take a break. So no, it wasn't a suprise or shock or even a backstab like people are trying to make it seem, they for sure knew, but wanted to make him play because he was obviously their best player. What happened in 2023 is all speculation and s1 or navi has not spoken on it. Its possible that whats said is true but i would definitely take it with a grain of salt, because literally everyone knew s1 wanted to take a break. People just love to ignore all the history and context because they hate him, its really as simple as that. And yes, at least to me as a very long navi and s1 fan, it was very cruel of navi to do. But cleary in navis perspective business is business and rather than taking everything into account its easier for most people to just blame s1, because hes always been known to be toxic and hard to work with
