They didnt want him to be a rapper, but not for some malicious reason. They loved his beats, but thought no one would care for his songs that were nothing like the mainstream rap at the time, especially since none of them were about bling/drugs/gang stuff. That's just what was selling. And Roc-a-Fella Records wanted their star beatmaker actually making beats for their star rappers, not "pursue dreams". So they allowed him to make that album, thinking the sooner he is done with it, the sooner he will get back to beatmaking.
All of this is confirmed by tons of other people affiliated with Roc-a-Fella Records (like Jay-Z and others) at the time.
They're in on the story.
Unless literally everything said about the matter by everyone involved was an extremely consistent lie that they all conspired to perfectly maintain for 20+ years and ongoing, I find it very difficult to agree with your statement.
Kanye has a song off his album College Graduation where he talks about his initial troubles[1]
