A total strawman and you know it.
Not half an hour ago I provided a link to an article that puts some perspective on the situation. Did you bother to read it? The point is that governments take ownership for reasons of policy. It's completely uncontroversial.

What Trump says or does is entertaining, but he isn't the moving part that matters. Pay attention to Democrats. Right now, they are doubling down on SOS even more strongly than the NDP in Canada. They're stuck in a "we weren't true enough to our principles/we didn't get our message out strongly enough" cycle.
You can prove anything if you make up your evidence. So far the US has acquired a 10% stake in a major corporation in a major strategic industry. There isn't much point riding the Slippery Slope Express all the way to the conclusions at the bottom.

What some critics (other than those dipping into the "Socialism!" well) are writing is that it has the appearance of negating the commitment by which Intel was supposed to build some fabs in the US - has money for fabs become money for stock? And will Congress do anything about it (noting that some Democrats will love a pretext for more muscular government investment in equities)?
