Yes, if you have a point to make you should spell it out. Google manufactures phones, has an open source OS and has a bunch of proprietary stuff that they do not release, see:

"However, most devices run on the proprietary Android version developed by Google, which ships with additional proprietary closed-source software pre-installed, most notably Google Mobile Services (GMS) which includes core apps such as Google Chrome, the digital distribution platform Google Play, and the associated Google Play Services development platform. Firebase Cloud Messaging is used for push notifications. "
