This one's an interesting one. First, their base is in the NW, so there are probably more Freddie's customers (my mom worked for them for 35 years) that like this political statement than not. (And don't get me wrong, this is absolutely a political statement). But it seemed like a hedge.
Any company can, at any time, change their business model and product line. And if Freddie's were to say something like "due to declining sales/market share/whatever with our firearms and sporting division, we're getting out of the firearms sales game and focusing on our other business units", I don't think there would be much of a ripple. Shareholder value trumps (no pun intended) a lot of things in business decision-making.
But to say specifically that a) it's due to Parkland, and b) they're getting rid of
magazines with pictures of weapons in them, is a political statement. Which, again, may work out well since they're in a very "blue" part of the country. But I don't think that the ones that sold weapons were.

Freddie's hasn't stopped having Newsweek on the shelves near the checkout counter even with its plummeting market share, quality of writing and poor sales. But if you're going to do that, why bring up "declining sales"? Which one is it?
It'll be interesting to watch...
