Your long rant aside. No busy corporation with teams are going to give up the Finder for Windows File Explorer. Don’t under estimate how useful labels and Quick Look are in team environments and anyone who thinks these features can be abandoned is a useless duffer. If someone in a company suggested abandoning the Finder I would send them straight for a 1 to 1 in a private office and they will leave that office with their head between the knees.
I've worked in dozens of very high profile corporations - financial, government, military, manfuacturing and retail. Not a single one has any Mac presence or footprint of note, and in fact the great majority have none whatsoever. None of the enterprise grade software I work with even has a client or agent for MacOS, there's no demand for it. Windows Servers and desktops, Unix (AIX, Solaris, HP-UXes etc) VMS, z/OS, Redhat, SuSe etc - yes. MacOS - no. If anyone came to me advocating the use of Finder in a 'busy corporation', they wouldn't get very far.
