Two issues, you can download and play your games in ‘perpetuity’ so long as Valve continues on the current operating model.
And Valve has not been particularly consumer friendly in the past.
They were found to be violating consumer rights in Australia at the very least and had to put a large notification on their storefront to disclose exactly what they had been wrong.
Valve were forced into providing a refund model and even then it often conflicts with consumer interest. Though admittedly bad actors will always try to abuse any refund model on digital products.
You’re not alone, I can hear CRTs, bad capacitors and an array of other electrical appliances.
I can still hear the high frequencies that only teenagers and your kids are meant to be able to hear.
