The US Tech oligarchs are certainly spending a fortune on corruption (ie lobbying) on national and EU level, however to mixed success so far. The biggest threat to us are Russia's fifth column, right (but also some left) populist autocrats. Those things are going hand in hand however. Those populists are ready to not only sell us out to Russia but to any foreign power willing to pay. Take the lead candidate of the AfD for the previous EU election. He was shown to have been bought not only by Russia but China as well. I am sure, he would have gladly worked for US tech oligarchs as well, if the AfD would not have frozen him out a bit, not for selling out to foreign powers but for getting caught red handed.

It is up to the voters to vote for or against those people. Sadly, my confidence in this regard is rather low. It is shocking how similar the 2020s are to the 1920s. I am not looking forward to the 2030s.
