This is by no means an official report, but rather the WSJ spoke to some people who are “close to the matter”. Basically the worry is that the more dominant Samsung gets, the more negotiating power they will have and could demand more online advertising revenue. The worst case scenario here would be that Google refuses to give Samsung an increase in revenue, in which case Samsung could always pull out and start making their own version of Android, much like what Amazon is doing with the Kindle Fire. Then again Samsung has Tizen/Bada to fall back on, so some are saying that the loss might be greater to Google than it is to Samsung.
Alternatively with Google’s acquisition of Motorola, the sources are saying that Google is trying to leverage that in order to ensure that Samsung’s dominance does not get out of hand. This is expected to be accomplished with the creation of the rumored X Phone which will allow Google to compete with other Android manufacturers in the market. This would make sense because current Nexus devices are being made by other companies, such as HTC, Samsung and LG. It will be interesting to see if Google and Motorola’s X Phone will change the playing field, so be sure to check back with us for more updates.
