Oh boy whats the deal? P2P functionality was introduced in various means into Windows since Windows XP with BITS.
This means that machines gets update faster especially in scenarios where bandwidth is limited or the connection is spotty.
You can opt-out, it doesn't touches your personal data, doesn't work on metered connections, the updates can be pushed out for as long as they are in cache (<30 days).
Updating 3-4 machines on the LAN is much quicker with Windows 10, SOHO machines that aren't routed into the internet or are heavily firewalled can be updated easily, and heck the vulnerability window for machines which weren't connected to the internet is much smaller now since they can grab critical updates without even being exposed to the internet which previously required backporting or having enterprise update software (WSUS and the likes).
The conspiracy theories around it are also quite silly considering that MSFT has complete control over the OS just as any other major OS vendor unless you tinker with it yourself.
