You are right, I am speculating, as was the poster of the parent comment. I certainly didn't mean to muddy any waters, but you have to admit that there have been things going on within the EU, that paint a bit of a bleak picture of how the table might turn if the EU had greater influence/power (in terms of aforementioned platforms and software) on the global stage.
And while you're right that the examples I gave didn't become actual law just yet, it's certainly not due to the EUs benevolence that proposals didn't materialize, but instead very much like in Mozilla's case, that the outcry from people had them reconsider.
However, I believe there were proposals that were put into law even though the outcry was there. (eg. Article 13?)
