knowing what the other half does is usually a couple clicks away on the web, a 'man ...' away in the terminal, sources are usually available at a similar distance, and most of these services can be stopped and (forever?) disabled with a 'systemctl stop/disable ...' (you might even go the extra step and apt remove them). Trimming down stuff that you know you don't need is a pleasure (assuming you know what you're doing), and the end result is a leaner, faster system. Eg. after I installed AnyDesk, I didn't like that it started with the system (I'm paranoid, and I'm only using it occasionally), so I systemctl disabled it. This doesn't stop me from using it when I need (that is, to assist others. In the rare events when I need remote access to my system, I just use a reverse SSH tunnel, which is more practical for me)

    Get-CimClass | ?{$_ -match 'service'}

    $svc - Get-WmiObject -Class Win32_service

    $svc | Get-Member

    $svc | Select-Object -Property Name, PathName, ServiceType | Format-Table

    $svc | ?{$_.PathName -match 'svchost.exe'} | Select-Object -Property Name, PathName, Description | Format-Table

What does svchost do?

And no matter "privacy is a human blah blah", apple collects a ton of data too - whether you agree or not.

(I will mention that ubuntu is not microsoft terrible, but it is starting down the path trying to force automatic upgrades and collecting info)
