It seems to me that in this situation, the bad guys are not the OS but
that they automatically have rights to any data you display on top of
"11.1 Content License.
(a) You retain copyright and any other rights you already hold in Your
Content. By submitting, posting or displaying Your Content you give
Google a perpetual, irrevocable, worldwide, royalty-free, and
non-exclusive license to reproduce, adapt, modify, translate, publicly

This means that if someone displays OS data on top of Google, he must
also be entitled to grant the requested license to Google.
All OS are doing is clarifying that a normal OS customer will probably
*not* have the right to grant others (Google) a "perpetual, irrevocable,
worldwide, royalty-free" license.
This is true for OSM as well; my reading is that we must not display OSM
data (say, a KML file we have generated from our data) on top of a
Google map, because the above clause would then give Google rights to
our data which are incompatible with CC-BY-SA.
In conclusion, if someone says the OS is "reinforcing its stranglehold",
then the CC-BY-SA license forces us to do the same...
