Because two US companies merging has also a big impact on the EU market. A US company launching a feature in the US but not in the EU has no impact on the EU market. So no, it's not the same thing.
yes, as I said not the same thing as effect on eu market, but the final effect is the same: EU has the power to block a merger of two us companies at it's will even if for us govt the merger is totally ok and eu can bend this power in any direction including forcing a foreign company to implement a global policy
