A first!!!

If I could control the homeworld facilities directly (*cough* SE5 *cough*), HWs would start with several entertainment networks. But alas...

But the homeworlds are generally full, so unless the AI can tear done facilities now to replace them with more needed/fitting ones, it will end up with maximum angry homeworlds and the according production penalties.

With even a low bonus, they get a 100% bonus to production; up to 400% bonus with high. And it only applies to the HW. The angry penalty is not that significant for them, in my opinion.

Also, there are the effects of ships:

Our Ship in Sector := -10
Our Ship in System := -3

1 ship in the same sector as the planet offsets a 1% facility penalty. I suspect it might take a while before they get enough ships roaming about to have an overall mitigating effect, but it could happen.

Btw, it looks to me like those morale penalties from the facilties are cumulative .. at least the +4 entertainment thingie didn't help me at all ?!

Yes, planetary happiness abilities stack.

Is there something upside-down with the happiness in between-nation relations?

The AI is insane.
