Was DRM added into the EGS version of the game recently?

I used to keep a copy of this game on an SSD (from EGS) to bench computers. I took the game off the SSD to clear space, and when I redownloaded it, it no longer launches from the .exe. Instead it tries to open up EGS if EGS is on the computer and hangs, and it also opens a browser window to the EGS store. Has anyone else noticed this?
