I kind of understand your comments, most especially in criticizing his possible lack of passion for the team.
I guess I'm wondering what the realistic alternative is. Owners are owners. With few exceptions, their primary motivation is to make money or use the franchise as a symbol of their wealth. There aren't many teams where I even know who the owner is, let alone how they influence the team.
Being that I live outside of Charlotte, the issue is probably less significant to me, as I don't have a stake in the community. However, as a fan of the team, I'm not overly concerned who owns the team as long as good basketball decisions are being made. Obviously, you'd love to have a vocal owner who supports the team and puts a positive face to the franchise. However, I'm happy enough to have an owner who chooses smart people to run the organization and gets out of the way. Johnson seems to be that kind of owner.
