Why wasn't Donald Duck in the original DuckTales?

There was a long period when Mickey did behave himself too well, but his early history is full of naughty and sometimes wicked behavior. Disney toned him down and he lost much of his appeal for me when they modified his eyes.

I have no idea where, but I heard they toned down Mickey to make him an unoffsensive mascot. He wasn’t even in many things for awhile. I guess after a few decades of that they thankfully changed their mind.
