Commodore struggled with same mistakes on negative rail in Audio section, but also somehow on highend expensive CPU board.
https://wiki.console5.com/wiki/Amiga_CD32 C408 C811 "original may be installed backwards! Verify orientation against cap map"
A4000 https://wordpress.hertell.nu/?p=1438 C443 C433 "notice that the 2 capacitors that originally on A4000 have the wrong polarity"
Much worse is Commodore A3640 68040 CPU board aimed at top of the line A3000 and A4000 http://amiga.serveftp.net/A3640_capacitor.html https://forum.amiga.org/index.php?topic=73570.0 C105 C106 C107 silkscreen wrong, early revisions build according to bad silkscreen.
Typical Amiga fanboyism and Apple envy, if a Mac does something they have to prove the Amiga outdid it. “Only one model with a reverse polarity capacitor? With Commodore it was a systematic issue!”

I think we're envious that Apple did a better job of engineering their systems
