If you’ve read my comments to the video, you know that I don’t think this to be a serious alternative. There are even more serious problems to solve than open questions with the inflation theory; to name the most important ones: Turning a crunch into a big bang, having a “decaying” dark energy to start contraction, contraction increases curvature, not the opposite.
This model needs a lot of work to get even close to convincing me (and probably others).

Sounds highly plausible, but so at this point did inflation. The bottleneck bounce looks like the point where the theory might most easily go wrong.
