They have no incentive to improve the site, because they’re a for-profit entity.

Despite the constant screeching for donations, the entire site is owned by a company with shareholders. All the “donations” go to them. They already met their funding needs for the next century a long time ago, this is all profit.

That's a serious accusation. Can you elaborate? What is the name of the company? Why does the Wikimedia Foundation claim ownership? And if you're referring to the Wikimedia Foundation, then what do you mean by "shareholders"?
