This may be related to Google's business model. Google's main businesses - search engine and advertising - both rely on an open web ecosystem. Therefore, Google has long maintained a friendly attitude toward open source and the open web, such as with Chromium, Noto fonts, Go, Flutter, and others. By providing infrastructure tools that benefit the open web, Google extends the reach of its searchable content and advertising. When the entire Web ecosystem benefits, Google ultimately benefits as well. This model also aligns with the philosophy of the open source community, where everyone is a beneficiary and naturally becomes a contributor.
