I agree with your main point that he hasn't changed
However, "BM is full of tech people ... not fascists" doesn't seem to parse
The tech industry is more defined by its right-wingers than it is by progressives. Management tells it differently, but pretending to be the victim is a feature of authoritarian cultures.
So if it's full of tech people (like Elon) that's the same as saying it's full of fascists and fash-adjacent/fash-apologist/etc (like Elon)
