Sentient Marmite: The Truth may make you fret.
You must mean some different Bill Gates. He's a philanthropist now, but he used under hand tactics to create a de-facto monopoly, and for many years OEMs paid a per PC DOC then windows fee, even if the PC was shipped with a different OS. His first product was Free Dartmouth BASIC ported by a friend in a short period of time to 8080 assembler. PCDOS/MSDOS was sold to IBM before it existed. They bought it (QDOS) from a company down the road that had ripped of the x86 version of CP/M (both done by Digital Research).Marx was against Mr Gradgrind, not Bill Gates, at least to my understanding.
Bill Gates even bailed out Apple so as to maintain the illusion of competition. The Mac was then (and largely now too) only a niche product and wasn't in reality competition. The only two genuine from scratch successful and really good MS Products are Excel and Word. Ironically delivered for Mac first as Windows wasn't yet working properly. Mac then was a MkII Lisa, it and Windows GUI as well as Amiga and DR GEM (on PC and Atari) were all copied from Xerox (developed in late 1970s). Current Windows is based on NT, derived from DEC VMS for VAX and the IBM OS/2 (1985). MS released own version of OS/2 in 1989 and 1st real Windows OS, NT3.5 in 1993. (The Win 2.0, Win3.1, Win95, Win98 were really only shells on DOS). MS ripped off a billion consumers and held back computing by over 10 years with their behind the scenes shenanigans. Which haven't stopped.
Instead of oppressing millworkers, Bill Gates oppressed consumers. Marx I think would be very unhapppy about Apple (US Marketing Co. using cheap Chinese labour), Google, Facebook and Windows 10 tracking and spying on people in ways that would have made Stazi and KGB envious. GCHQ and NSA spying wholesale on their own people. Marx if still alive would be writing a very different sequel to Das Kapital
Much of the worst excesses of Capitalism are in the end self defeating. Much of what upset him (like Luther and Catholic Church in a way!) has gone anyway with no revolution or communism. Communism has proved to be unscaleable beyond the size of a small Kibbutz, which don't work as efficiently as the hybrid Capitalist / Socialist Moshav. The USSR never really had Communism as envisaged by Marx, nor has China. China today is more like a socialist version of pre-1912 Empire.
Perhaps there are interesting parallels between how the the German Princes exploited Luther's teaching for political ends and how Lenin and Stalin exploited Marx's teaching for political ends.
