Replying to myself since it looks like the replies are making mostly the same point.
> what if fb wants an exclusive, no privacy App Store for itself? What about it? Let them do that. Let the consumers decide? I chose Apple only and only for better privacy controls in the OS, not in the App Store.
> dominance of chrome Chrome won because Firefox and IE were worse. A lot of improvements in Firefox are thanks to competition. Safari is still number one browser on MACOS. I agree with the point that google might make things incompatible for non chrome users. Then they will be hit via these same regulations.
