I guess if they could steal the bikes but leave an identical copy behind so no-one knew in between buying their own bikes when they can afford or find them, or while they pay over the odds to borrow a bike from one company and want one from another and can't pay for both at the same time.
IIRC vhs hire was about £1.50 mid eighties and a cinema ticket was similar.
As such £5 to£10 streaming fee seems reasonable compared to a cinema ticket these days. Given the film industry and cinema model is struggling I don’t think watching pirated movies is an ethical activity.
