I agree that SICP is valuable, and years ago, I tried to help make it accessible to people on low-powered computers [1], and to help preserve software support for it [2].
I don't know all the rationale for MIT's moves to other things, but the decision we can see seems plausible to me. (Python is a lingua franca at the moment, popular in ML and data science, still somewhat popular in Web, and very easy to pick up. Even language-nerd me wrote some production Python code that moves large amounts of important data around.)
I agree that modern Scheme (perhaps starting with Racket) seems like a great platform for much of CS-ish education, and for a lot of research and development. I also agree that putting substantial MIT resources behind building out Scheme/Racket seems like it would've been huge. Maybe that will happen.
A lot of MIT behavior emerges from that of individual faculty members and senior research staff, who have some degrees of autonomy. MIT has also prided itself on being big on "experiments", and not having rules that might get in the way of someone exploring ideas. If you have the opportunity, you can try to use that to help make things happen.
