How do you know this? Why would they proliferate smartphones and internet and antibiotics and vaccines but not free energy?

Not to be cynical, but because people who run things make a lot of money from smartphones, the internet, antibiotics, vaccines, and paid energy.

We could have had free energy a long time ago (Tesla, the guy, not the company) but the wealthy men of that time (also energy guys, BTW), didn't want a free competitor. And still don't.
