Sure razer programs are super sketchy, but a convenience program I never installed should not touch ANYTHING unless I tell it to
That's not the point I was making.
It was: OneDrive, normally, doesn't cause any such issues. The fact that these issues exist with specifically Synapse is more probably due to Synapse being shite, than OneDrive doing anything.
They are writing constantly to documents because it makes it obvious to the user where the logs are, why do you get to decide they don’t get to write there?
Because Documents is the user's documents space. Temp files go in Temp, application data goes in AppData. It's a super simple system that worked on Windows for the past 20 years. Razer doing things wrong is a problem with Razer's products, not Microsoft's.
For example openmw a huge project puts logs there
Then the devs of openmw should be flogged too. Everybody should fuck off from the Documents folder, because it turns into another Temp/AppData with all the crap that I didn't put there. It's My Documents, not "trash bin for lazy devs".
I won't argue against it reinstalling itself as I never had a problem with it just chugging along and giving me the 5GB of free backup space.
I won't comment on the performance hits, because I never experienced those. I'm willing to bet the fault is on either the user or the software their using, though, because I haven't seen a performance hit on any of my 2000-3000 managed devices. Sure, OneDrive for Business uses SharePoint, but the app works in a similar way.
I won't comment on your last paragraph too, because it just reiterates that you missed my initial point.
