They'd better be a little concerned
https://www.reuters.com/graphics/EARNINGS-AUTOMATED/NFLX-OQ/...I really wonder if they genuinely think all the broke and massively in debt college kids on their parents netflix accounts will just fork over the cash for Netflix's ever increasing monthly fees and that they have data showing that it'll make up for the loss of subscribers and viewers this will cost them or if there's a CEO caught up on a sunk cost fallacy or something. It seems like this couldn't come at a worse time for netflix considering that there are a growing number of competitors with better offerings for less money, netflix has been getting objectively worse, piracy is easier and more affordable than ever, and a huge amount of things that aren't even streaming television are competing for our attention.
Low cost, convenience, and having a decent catalogue of content made netflix what it is today, but today netflix is getting more expensive and less convenient, while their library struggles to have enough worth watching to keep people around all year.
