Well the same could be said about any new service that requires a specific (new) technology, no? In theory it won't be device lockin in the coming year(s). Your objection seems a bit silly at the present time.
Now, if Google has this technology licensed and only they themselves are allowed to use it in phones.. then you'd have a valid argument.
