Long story short, there were two main issues that people had with Epic:
- they made exclusivity a thing inside pc platform (this was the main issue for most people)
- Tim Sweeney is generally disliked
The first issue speaks for itself. The second needs a bit more context.
Tim Sweeney has an history of being arbitrary. One year he says one thing, the next another. Relevant to this case, Tim was openly against PC gaming back in the day, while Valve was pushing for PC gaming. We’re talking around 2010, where console gaming was predominant, most publisher favored consoles against PC. Valve at the time was one of the few companies betting on the PC platform.
Now, he’s suddenly pro PC gaming. People see this as him doing a 180, and trying to take the spoils from Valve’s work.
Then there were also some comments that he made that aged like milk, but generally speaking this is why people take an issue with Epic but not Steam
