I think op needs to clarify a bit more about what he is actually talking about. There is a lot to discuss when it comes to exclusivity.
On the console side you have games that are made and published by Sony/Microsoft/Nintendo themselves, the development studio is owned by the parent company. These games are one of the most important things to a company that makes console hardware, it's generally what helps sell units. I know people will say "but what about MS, they release their games on PC and Gamepass!!!". Let's be honest here, if MS' first party games were selling as many copies as what Sony and Nintendo were selling they wouldn't be going down this path, they wouldn't need to.
If Epic owned any developers and had their games released exclusively on the Epic game store there would be no uproar
by the majority of PC gamers. I was perfectly fine buying a game by EA on the Origin store as the games were made by them and it was the only place to buy them. Same with Ubisoft and their digital store front.
Then you have exclusives where Sony/Nintendo/Microsoft does not own the development company but they like the idea of the game (or the idea of an IP they own) and they fund the production of the game or provide advertising support for the game. Again, I think these games are fine to have exclusive as they are footing the bills. Again, if Epic would fund these games from the get go there wouldn't be an issue at all for the
majority of PC gamers. Same goes for EA and Ubi.
Then you have exclusivity bought titles, meaning that Sony/Nintendo/Microsoft did not help fund the game or advertising. They literally paid money to make the game or DLC exclusive to their platform. This is basically a dick move and is not ok. This is almost what Epic are doing now and it is also a duck move.
No Man's Sky is a bit confusing for me, I know that Sony had some sort of financial stake in the game but I'm not exactly sure what it was. If they helped fund the game than everyone else who loves and plays the game (on platforms other than Sony) should actually be happy that this was allowed to happen. I they only covered advertising costs, see my second paragraph but again everyone should be happy that the game was allowed on other platforms. Sony were a bunch of dicks for allowing the advertising that did happen for this game though, that's on them IMO!
Something that Epic were doing was "stealing" games away from other PC platforms. As mentioned these are games from Kickstarter and games that were close to release. This is akin to a game being advertised for PS4, Xbox and Switch and then 2 weeks before release Sony pay a massive sum to keep the game on their console and then EB Games etc having to tell gamers that they can't get the game on their chosen platform anymore. DICK MOVE all around.
Finally we have third party games by developers that only target a single platform without any financial benefit from the platform holder. It's wholly their decision and this is OK if they decide to do this as they don't have the resources for multiple platforms or they deem certain platforms not worthy of their time. If developers on PC were choosing the Epic store on their own accord without Epics intervention this would also be ok as it's what the developer wants. Unfortunately we know this isn't true as pretty much every Epic exclusive game has openly admitted that their is a deal in place with Epic.
So Epic = DICK MOVE ALL AROUND
