Despite paying for Netflix and Disney+ and Prime and etc, I have pirtated 1080 copies, with subtitles, of all our favorites because network access is unreliable and service provides add and remove media without warning.
As has been said before, the pirated copies are frequently a higher quality product than is available for purchase or rent.
Disney+ is notorious for this. Disney also has a number of shows that they refuse to provide on physical media. If they are removed from their platform and not licensed elsewhere they effectively become lost media.
