Look at China's example, their GDP per capita increased by 300% in the same time span. Suddenly they started being seen as a threat, companies banned, broken up, forced to be sold. This move is probably motivated partly by similar reasons and is indirectly supported by the fact that the US considered this a viable strategy.

The other reason this is being considered is the deep distrust of US tech companies. For the average literate European citizen, US tech companies probably look just as bad as Chinese companies look for the average literate US citizen. Again this is indirectly supported by US reacting in the exact same way towards the party they distrust.

This being said I don't think this will pass and it certainly won't be put to use any time soon. There are still to many strings attached from the US to European countries, economies, and people. The purpose of all that spying and infiltrating everyone is to keep both allies and enemies in check. But recent US moves and changing of times have created some very obvious cracks that won't get mended too easily.
