Yes they are.
There is big money to be made and they are making as much as they can while they can
From a business POV, is it better to really pump out everything until the demand is finally sated, or is it more profitable to keep manufacturing quotas just short of what is needed to continue the shortage and keep the prices up?
I’m only asking because the length of time of the shortage seems to be getting a little long in the tooth for it to be a real shortage.
