I don't see where the complaints are coming from. Standard mystery stuff in the intro and I thought it was fine. "We have fragmented info and the Kree are ok with the Framework we got running, but Quake caused the Earth going boom!" is pretty much setting shit up for Daisy didn't actually do it. Plus, let us not forget that some alien dude arranged for their capture and transport to the future, but Fitz (the one tech genius) was left in the present. So we are left with a few possible choices
What version of time travel? Multiverse or the predestination paradox "this always happened" version? If they go with the former, that makes things easier.
If it is multiverse, then I would bet that Fitz in an alternate timeline arranged for the kidnapping. He specifically leaves himself, knowing that /w Simmons missing, he won't stop until he fixes the problem. Of course, the future they are in is the future of the timeline where they got kidnapped, which means Fitz didn't succeed directly in stopping the destruction of Earth. However, he could have left enough information hidden to allow for the future team to discover them and enact his plan (maybe).
I've watched enough of the show to know you can't take the stuff at the start at face value and they are going to pop some reveals later on as they develop the story arc. I also doubt they will do this a full season, since they usually enjoy splitting their seasons with different story arcs (like the Ghost Rider, LMD, and Hydra World arcs).
