I see
no indication that the current admin has any interest in that. If the stolen funds will ever be dispersed back it will be a fight. Which will hit smaller companies more than larger (hiring lawyers and investing resources will cost money now, against a potential return likely much later).
Even if they could identify who paid more and exactly how much more it seems unlikely because they need to hedge against future uncertainty. The admin doesn't want to give up their toy (its been a vehicle for unprecedented corruption and power) so its definitely not something they will lightly surrender. If it were my business, I'd be wary to spend any refund until it seems certain that the government won't try and steal it again.
Best we (as cyclists) can hope for is that once all the tariff nonsense and uncertainty goes away, prices come back down. The cynical response is the old adage "costs go up, prices go up, costs come down, profits go up". But the cycling industry is hurting and its likely a lot of companies would love to be able to reduce prices.
