I wonder who might have initiated them (maybe Apple and Microsoft?).
The allegations revolve around the infamous agreement manufacturers have to sign if they want to include any Google apps in their Android devices (including the Play store, Gmail, Youtube, etc...). If you don't know it states that if you want to include any of Google's apps you must include a certain group of them (it was around 15 I think). It also states that you shall not develop any Android forks.
I do agree this agreement is abuse of power and I'd really like it if this resulted in we being able to uninstall (without rooting or other trickery) Google apps from Android devices, even if it means I have to pay some money to Google for the base OS.
