Apple is worse in many ways. The situation with Safari on iOS with it being the only rendering engine you can use is akin to Microsoft forbidding other browsers on Windows and only allowing browser skin UIs that sit atop IE6.
I've reported numerous iOS bugs in the webkit project and most of the times I never get answer.
I also frequently report bugs in the Chromium project and I usually get an answer in less than an hour. Never a bug I reported was ignored, legitimate or not.
Recently I wrote an article criticising iOS from a dev perspective and posted a tweet from a core webkit member:
> that's because they have a lot more engineers and evangelists/dev-rel than Apple
...referring to Google and the Chromium project.
Well, hours after I published the article the Twitter user was deleted.
