  <p>what if anything should we do about it?</p>

<p>The short answer -- nothing. We (the community) had the possibility to set up an independent site using any freely available StackExchange-like engines (there are quite a few of them). Nevertheless, due to many reasons (reputation of SE, lack of an opinion leader, etc), we voted with our feet and came here, to StackExchange. By doing this we have to accept our hosts' conditions. We can ask them politely, but at the end of the day it's their call. And it is ours too. "It's a free country" -- anyone can set up a competing site and try convincing people use it, instead of SE. I'm very pessimistic about this option though.</p>

<p><strong>EDIT</strong> When I said "it's a free country", I meant that we can move to another site as a block. But you know what? It's not gonna happen.</p>
