I really don't like it then. So we could theoretically have 4 or 5 totally closed platforms with small market shares for each and that would be totally fine.

I guess that the issue is that I am not as much against Google using Android to distribute its services (I would be using most of them anyway and those that I don't use (newsstand, spaces, ..) can be replaced anyway) but against being unable to distribute/install whatever software I want on a general purpose computing device.

And AFAIK, sadly there is no law governing this.
