8 core 64 bit ARM chips with GPU built in are fairly common and 10 core chips already announced (Mediatek), with 16-48 core vaguely hinted at for servers by other vendors
A bit more than hinting: Cavium is selling 24-48 core ThunderX (ARMv8) chips. I think the first one shipped a month or two ago.
But what can they do to be more open than they already are
They can allow OEMs to install Google Play without requiring that they install the entire suite of Google apps and without preventing them from installing competing apps.
There have been allegations in the UK of voter intimidation after postal ballots became easy to obtain: people would require dependents to hand over their ballots, fill them all in, and post them back. Now, it may be that this didn't happen or wasn't statistically significant, but if people are not required to turn up and vote in such a way that they can't prove to someone else how they voted then there's the potential for doing this on a large scale.
Of course one solution would be to allow individuals to vote repeatedly but only count their last vote, though if you capture someone else's voting credentials then it's very easy to vote en mass with everyone's details at one second to the closing deadline...
None of their competitors even OFFER the option to have an "F-Droid" or to remove their respective equivalents of play services
I'm not sure what your point is. 'Other people are worse' is not a defence in an antitrust investigation, unless those others have enough of a market impact that you're probably not going to be in the antitrust regulator's jurisdiction anyway.
Google is using the fact that they effectively have a monopoly on application distribution (yes, I know about F-Droid and the Amazon store. Most apps I want come from F-Droid, but I'm hardly a typical user and the rest come from Play because they're not in the Amazon store) to gain market share in other areas.
