Why should there be pushback against antitrust measures?

It's what keeps markets alive

Well, not necessarily; lots of things keep markets alive, including making it easier for people to start companies. But that aside, it's the selective enforcement of antitrust measures that's my point.

If those companies then got smothered or acquired by big oligo/mono polies, that only gets you so far.

What is selective about it? I linked in the sibling comment a fine for the biggest European digital ad company. And it's trivial to find the EU blocking anticompetitive behaviour or potential for it in every domain. Alstom and Siemens wanted to merge their train division to create a European champion in train manufacturing to better compete with Chinese companies, and they got denied. Because for the EU competition in Europe is more important than EU companies being able to compete globally (because the EU market is in their purview, global ones are not).

Where is the selective enforcement?

They also enforce antitrust in other sectors than big tech. You just don't read that much about it in the news
