On the one hand, yes that's a potential issue. On the other, hasn't Google been very good with making sure their Android devices (e.g. Nexus *) are pretty open? That was my impression. Of course, I don't follow this super closely. Moreover, all this is relative--and relative to Apple, even Microsoft seems open. So Google has a rather large spectrum of openness where people would think them open just in comparison to Apple and Microsoft.
