Current market wise, I wouldn't be surprised if the Netflix situation is people canceling their membership to spend that money on a different streaming service, and then swapping between friends to get the union of shows for a similar $/month. This would explain both pushes of membership going down, plus them wanting to crack down on sharing.
ehh, It's more like a speedbump than a storm. There's too much money in the game for it to end up being caught in a hurricane.
I just see the other side on how piracy can also harm more niche mediums and discourage businesses from even bothering to compete, which is why I can't even say piracy is a 'meh' at worst.
The manga indusry outside of Japan has this problem in that it's 5+ years behind the already decade outdated online solution for digital comics. Several JP storefronts for phyical and digital manga, but that is almost non-existent in English. Manga is fantranslated so fast that there's no incentive to bother having official localizers outside of the already huge works. Easier to cash in pennies on anime adaptations and merch sales afterwards.
and the thread here as a whole is rebuking the argument that Netflix is losing money because people are pirating. Most people don't or can't go through this work, so that likely isn't the reason why Netflix is seeing drops.
