The track record of Facebook and Google may be better because their open-source strategy is to never open things that are core to their business. Projects like React will not give you a competitive advantage to build a Facebook competitor.

The issue with VS Code is that it opened the door to many other editors, which, in a sense, drive people away from the Microsoft ecosystem. The combination of VSCode, GitHub, and TypeScript is ideal for MS: they win by attracting companies to GitHub services (which also offer code spaces based on VSCode); they also win by attracting users to Copilot, which helps them improve their tools. Creating an editor like VS Code is expensive; they are not paying the core developers because they prefer to give away money. They do it because it's part of their business strategy. You don't pay for VS Code; companies that subscribe to GitHub services do. A VS Code fork circumvents that strategy.
