I'd be a bit concerned too. I have got the distinct feeling that over the last ten years or so Lego has been working harder to control both it's image and how the fan community uses its products. Stuff like suing YouTubers for a variety of reasons and being ever stricter about how and when you can use the Lego name.

My concern would be that Lego will make BrickLink the "approved" community and resale site and make it harder for alternatives to exist.

I hope I'm wrong, but I cant help but think that because the resale/collector value of Lego increases it would make sense for Lego to try and control that market.
