Can you tell me what you are basing that on?
From my long experience with browsers, Google is beating the other main browsers primarily due to competence. Microsoft, Apple and Mozilla have huge teams, and each has their own marketing advantages.
0. Competence at security. Chrome is unbelievably secure - although perhaps this says more about Google tooling and culture than the Chrome Dev team. My impression is that Mozilla and Microsoft have struggled to be secure.
1. Competence at fixing bugs. Chrome absolutely creams the competition here (I have much experience with this. Chrome is amazing, Mozilla is middling, Apple and Microsoft are hideous).
2. Competence at avoiding regressions. Chrome seems to be fabulously reliable software considering its complexity and development velocity. Safari and Edge have given me many many headaches with odd breaking changes.
3. Competence at delivering to wide range of hardware and OS versions. Chrome has hardly given me any problems with Android or multiple Windows versions. I wish I could say the same for Chrome's competitors on their respective OS. Safari only has to deal with known hardware and OS version, yet I regularly discover weird composition faults. I don't know much about Firefox here.
4. Many other organisations break down with large dev teams: Google breaks that trend. That's institutional competence.
> And ultimately, Google employees have control over what gets upstreamed and which contribution gets rejected.
So alternatives? Community edition run by W3C? Socialist version funded by a Google tax? Tongue in cheek, but you seem to imply we should tell Google how to run their operation differently.
As to the issue of DRM, why are we blaming Google for the DRM agreements that economically it had little choice to accept? Everything I have seen implies that the copyright barons are forcing Google to support it. Out of control DRM is our collective failure to control some powerful copyright lobbies. I am not a fan of DRM (or huge copyright terms).
I too am sad that other browsers are failing to compete with Google. I especially want to see Mozilla succeed. But I think we should recognise the skill of the Chrome Dev team.
