I think it's always been free but definitely for the last 18 months or so. From the EAA forums, Solid Edge sub-forum back in Aug 2023:
"2. After the SOLIDWORKS debacle, I'm a little gun-shy. Will Siemens want to put their hand in my pocket a couple of years from now, once I've invested time in learning their software and drawing my projects?
That's a great question. The license you receive when you download SolidEdge is valid for 3 years. After that time, you will be asked to "renew" the program, but Siemens has stated that this will be at no cost. This means that you can continue using SolidEdge indefinitely, as long as you renew your license every 3 years."
The "3D experience" (aka CAD Software) that apparently everyone hated was EAA's offering of Solid Works, not Solid Edge. I've not used either so have no opinion good or bad.
