>The new way is you give them your credit card or WeChat 'bill me' code. You get billed whatever the merchant wants to bill. Any post-facto complaint will be at the cost of your own time. Sure, that may be the "new" way, but that doesn't mean it's better! Much of the payment fraud online couldn't exist if customers were in control of how much money to send and when rather than the merchant. >Under Windows, AFAIK most programs have a partially restricted permission set, hence Run as administrator. In Linux, under modern distributions, most programs run in both a user and a cgroup context, and some under further restrictions such as chroot and caps. Under normal circumstances, they're restricted only to the extent that your user is restricted. That's far from the level of granularity that GP is talking about.
