Has anyone here ever taken one apart? I’d like to know if the grey metal piece that actuates the guide can be removed from the main plate.
I don't think that piece is removable. See

For the "pardo.net" site, the secure version doesn't work on all browsers. If it doesn't for yours, simply edit the link to remove the letter "s" in "https" and it should work.

See link above. In addition to the relatively thin - and thus not terribly strong - wire serving as one of the parallelogram plates (reportedly about 1mm in diameter), the Superb Tech also supposedly had issues with pivot wear and their internal springs. Plus, per the above link some versions also used the same sprung pulley design as did the MounTech, with all its issues.
The SunTour "Tech" derailleurs were also apparently a royal pain to reassemble once disassembled.
Neither the late Frank Berto or Mike Sweatman (who runs the Disraeli Gears site) had/have much good to say about the Superb Tech's design.
