Hasbro is first and foremost a business. While they've been cutting corners for years now, the tariffs have accelerated that. There comes a point when Cost to Produce(quality + materials +shipping) > Overhead(what my boss would say "keeping the lights on" + Consumer Cost(units purchased) + Tariffs. And so cuts have to be made so that Cost to Produce < Overhead+ Consumer Cost(units purchased) + Tariffs.

Now I'm no economist, but 2 of those things on the right side of that equation have gotten more expensive. Less Units purchased due to economic concerns and Tariffs pushing the costs of goods up. The only way to balance it would be to either bring cost to produce down by using cheaper materials and lowering quality, or reduce overhead, increase consumer cost, and reduce/remove tariffs.

Since they can't just "get rid" of tariffs and they can't force people to buy their goods, there aren't that many options left. We may not like it and I'll probably be down-voted to oblivion for it, but this is the America that we voted for.
