Google is a multinational corporation. It is about profit.

That website is limiting your blog's vocabulary because of profit; they are choosing google ad income over your freedom of expression.

I too bemoan the impact of corporate profit on media communication of all types.

But I fail to see what it has to do with political correctness. Google has determined that they will increase profit by enforcing those guidelines.

Corporations will deny dying people drugs, deny children housing, deny free water to ghettos, and perform countless other immoral heinous acts for the sole purpose of maximizing profits.

And if they can get people to blame 'political correctness' for this behavior, or immigration, or abortion, or whatever... all the better.
