Sony basically says we can take away anything we want from you whenever we want for whatever reason we choose without notification and you can't sue us because you had to have sent us a letter 30 days from first using our product to opt out of our binding arbitration from an arbitrator of our choosing.
You have no rights if you do business with this company. They get you to surrender them at the door by burying that fact in a bunch of legalese. Sony isn't unique in this either they're just the company bold enough to give their paying customers the finger and give zero fukks how it looks when everybody sees them do it.
Most companies have enough shame and wherewithal to know that taking stuff away from paying customers with no recompence is a PR disaster so they do something to ease the optics of it.
