That’s not entirely true. Everyone forgets there was an individual mandate penalty that his administration & congress repealed.
Anyone remember how the ACA assessed a tax on those who were not insured? (with income based exceptions). The tax was meant to feed into the ACA and keep plans in the marketplace cheaper, and to stop the program from adding to the federal deficit.
Once the trump administration came in they worked with Congress to eliminate that tax penalty.
Here is a helpful article that talks about the penalty and what the early findings showed when it was removed.
I found 2 resources I believe I can trust. There is a snopes article that lays out the basics.
Plus a local NPR station podcast in San Francisco that goes over the whole document in 13 episodes. I’m only two episodes in so far.
I don’t think I actually want to read the 900+ page document.
