alt Hacker News2 anecdotes about Logitech software:
I had a high-end webcam that flickered. There should be switch in the software to switch from 50hz to 60hz that'd fix it but it was nowhere to be found. After digging deeper I found that it was only available in English version of software. It was before macOS had Setting to set language per app, so I had to manually replace Polish bundle with English one through binary.
Another one: Has K810 keyboard that started in "FN-by-default" mode. K811, Mac version of said keyboard allowed for changing default setting just as K810 on Windows, but K810 on Mac - no dice. Support told me to shell out 200€ on Mac keyboard so I ended up writing small binary switcher [0] that would run after keyboard got connected [0].
