That’s certainly what you’re talking about, whether it’s profitable and thereby rational or worthy of consideration.
That’s not the only lens available, it is just the default setting.
The episodes I’m talking about were produced with a lotta public money, up to 1981. The show had high ratings immediately and kept them. That public start contributed to the ip value of today such that the resource of putting them up digitally, not remastered (not selling things here) for public consumption doesn’t really compare.
That single lens does want you to use it exclusively, it can’t require it.
