I don’t use Google as my programming language or standard library. (Of course, such a statement is nonsense.)

I have used Google as my programming language (Go) and a de-facto-standard library (Guava). Of course, in both cases they're open source. And I've found and fixed bugs when I couldn't get Google to do all of it themselves. And if Google ceased to exist both of these could continue with minimal interruption.

You replied to a different question, and declared that question nonsense.

My question is: do you use Google?

Yes. Now what's your point?

At the question: "Why Aren’t You Using Our Technology?" you replied "It’s not open source." It's two comments above this.

No one asked about programming languages or standard library (except you when you misunderstood my question).

Therefore you implied that a good reason not to use a technology is that it's not open source. Literally.

Then why are you using Google?

The original commenter did not claim to exclusively use open source software, but only that they have a clear preference for open source.
