we saw this exact playbook with ios 7. i don't think you need to attribute malice or read into it much.
ios 7 relied heavily on blurring effects-- a flex at the time due to the efficient graphic pipeline vs android they had. this was coming off the heels of Samsung xerox'ing and they wanted a design that would be too expensive for competitors to emulate without expensive battery hit. liquid glass is following in this tradition.
and similarly to ios 7, the move to flat design was predicated on the introduction of new form factors and screen. flat design lent itself well to new incoming screen sizes and ratios. prior there was really one or two sizes and that was it, easy to target pixel perfect designs against. as apple moves to foldables and more, this design flexibility is once again required.
as for no one trying to emulate it, i'm not so sure, OriginOS 6 ripped it off back in October.
