Big tech owned companies and subsidiaries

I’ve been writing about privacy a lot and since I’ve been dropping data hoarding big tech services, I’ve decided to compile a list of companies owned by Google, Facebook and the likes that are marketed under entirely different name, but essentially operated by these big tech corporations, so people who want to avoid these companies as much as possible can do so without much effort or guessing.

The list generally won’t contain every single company they own, I’m in particularly interested in companies and services that are widely used by people, but aren’t aware they are owned by said big tech. For example, Onavo has been quietly marketed as independent company while it was already owned by Facebook for years at that point. Or my recent discovery that Crashlytics is owned by Google, which is used by many 3rd party services and apps and people don’t really know it’s feeding data to Google.


  • AdMob
  • AllPay
  • Crashlytics
  • DoubleClick
  • Orkut / Hello Network
  • Waze
  • Widevine (DRM used by Netflix)


  • Instagram
  • Oculus VR
  • Onavo
  • WhatsApp


  • MoPub
  • Periscope


  • GitHub
  • LinkedIn




To further expand this list, I would like to ask you the readers to supply me with further info down below in the comments section and I’ll update the list to keep it as up to date and extensive as possible.

    1. The problem with these lists is that they list just EVERYTHING these companies have ever bought, including 90% of companies that god dissolved and absorbed by the parent. I’m more focusing on those that are still run as stand alone companies tot he public, but are actually owned by big tech. Thx for the Waze though, it’s going on the list.

    Recently…….it came to my notice that “HavocOS” ,an android custom rom had been busted by freelance cybersecurity researchers & pro- android developers.,……for secretly & stealthily integrating/baking rogue malware apps,,keylogger apps,,screenlogging apps,,,DNS re-,routing mechanism etc etc into each & every device build…….& then finally compiling the original source code & underlying API,,firmware with these malware apps

    There are even mutiple (dozens) of threads on reddit….regarding the authenticity of HavocOS custom rom
