The reason this policy is being pushed, is because some nations have benefitted a lot from US tech companies, eg Ireland, while others eg France and Germany, are jealous that they're not getting their spoils (while simultaneously seeing no large domestic tech company creation). France and Germany have vast influence over the EU, they regard it as their little fiefdom of power. To watch Ireland become richer and richer and richer by the year, as their GDP per capita just keeps soaring ever higher, drives those sleepy giants crazy.
GDP per capita
Ireland: $68,000
Germany: $44,000
France: $39,000
It's pretty obvious what's going on.
Ireland's economy has tripled in size in 17 years.
France's economy hasn't net expanded since 2006.
Germany's economy hasn't net expanded since 2007.
I seriously doubt France and Germany - both high corporate income tax nations - want to see a bunch of Irelands further sprout up in the EU, pulling even more economic benefit away from the power duo in the EU.
