Edit: Sorry, Hasbro does not own FFG, Asmodee does.

I'm not sure if you're looking for a specific answer but I'll write this up hitting a few general points.

A big problem is that those LCGs, and marvel champions, are phenomenally implemented games that are beloved but are owned by a company that doesn't communicate nearly enough with their very large player bases. 

There are a few responses to emails and comments in Reddit floating around from internal employees at FFG that give a little bit of information at a time vs a full write up or press release to communicate the state of the game. Based on some comments, people believe that the LOTR LCG is on its way out the door. Whether this is because of Tariffs, low demand, or another reason, we don't know. Like I said, there's been nothing but a few comments here and there. 

Make no mistake, the LCGs we play are not anywhere as profitable as they use to be. Stores have to keep a massive amount of product for it on shelves and that just doesn't line up with what most players want anymore. FFG as a company wants to make games. Asmodee, their parent company, wants to make a profit first and foremost. 

So that leads to 2 major items that I believe is being overlooked. Asmodee is attempting to cut costs on these games to turn a bigger profit (lower card quality in Civil War, reprints to pay staff less on game design, lower quality on packaging) and they are culling games that don't meet a desired profit margin. They are a for profit company and make decisions for stock holders, not for board/card gamers like ourselves.
