I'm sorry but i'm not letting you tell me what i should think is okay and what is not. If i think it's shitty, then i can think it's shitty. End of story.
Actually there's no difference, this is business at the end of the day.
Ready at Dawn made PS exclusive games for years, but this didn't stop Facebook from buying them after releasing successful VR titles; using this logic, then Oculus/FB shouldn't have bought RaD because they didn't have a long history with them? Same goes with Sanzaru Games.
Having history with a platform holder does not mean you are going to be tied to them until the end of your days.
Bizarre Creations was making games for Xbox and was swallowed by Activision.
BioWare had this deal with Microsoft for three games if I remember correctly, and before the first game was even out, EA had pounced.
Double Helix was making Killer Instinct one day and the next they were owned by Amazon.
DICE was making Xbox games, the next day they were owned by EA.
Angel Studios was making games for Xbox, and some time later they were acquired by Take 2.
Microsoft made a lot of dumb decisions in the past, and I for one am glad that they are being proactive when it comes to gaming. If some feel that it is shitty, so be it, no one ever got anywhere in the gaming industry by playing nice. Even Sony that is so often praised got to where they are by leveraging their financial strength as an electronics giant, buying a publisher, and securing exclusives that had appeared on other consoles prior.
