iirc, ublock also blocks api.google.com (i guess it's the analytics javascript files?), which incidentally, also breaks a lot of sites that uses the google common javascript library CDN (which servers stuff like jquery etc). I whitelisted it and it seems to unbreak some stuff.
There is no filter which matches "api.google.com", so this can't be blocked, unless you have a custom filter which does that.

uBlock uses third-party filter lists such as EasyList, EasyPrivacy, Peter Lowe's, etc. It won't block more than what is spelled out in these lists. Un-select whatever filter lists which you think should not be selected.
As I have said countless times now, uBlock will block as much as ABP blocks when using same filter lists.
As always, if you think something is blocked which should not be (for example if ABP with the same lists has a different behavior), I need a URL, a test case in order to be able to infirm/confirm that the problem is with uBlock and not with the filter lists. On that ground, uBlock has been quite stable for a while now, I don't remember the last time something was blocked which should not have been blocked (or vice versa) as per filter lists.
I usually wouldn't notice a broken website with ABP, but with ublock I see something wrong at least once a week.
