I've maintained in house forks of major code bases with a handful of minor code changes while we've tried to convince upstream to accept them.
- You can buy a reasonable wheelchair for moving people relatively short distances across flat surfaces for less than $1000. E.g those used in hospitals and for the partially mobile.
- You cannot currently buy a reasonable self propelled wheelchair for full time use for less than $1000 (give or take the manufacturer in the article).
Vs the one from the hardware store could have come from Alibaba and be a plastic core with a thin coating of metal for all you know.
We probably want to be sure if gas imports are heavily hit again or a major interconnector goes down we'll be fine before entirely demolishing it.
The camera app on your smartphone likely searches for them by default. That means feeding at least 1-2 frames a second through it.
Basic pattern matching for the position markers is a rounding error overhead vs processing a video feed. Fancy computer vision is not - on lower end devices you may not have enough resources to do both and on higher end devices it'll still impact power usage.
A bank robber, terrorist or totalitarian state could benefit significantly from bringing down all cell phones in the area for a few minutes (or even just crashing them in a loop as they boot up).
Or for some mayhem just stick a few of them under seats on public busses / trains set to activate at the same time.
Similar problem with GPS being used for clock sync in mobile/cell base stations in much of the US. You can buy an (illegal) jammer off Ali express and bring down a tower for very little money.
You need to cover your ass, but you don't want to actively push back and risk losing the sale.
So you either need to support SMS or several of the major 2FA app providers including the crappier implementations like Microsoft authenticator.
But now you have a released lock and a client that thinks they have the lock.
There is also regulation in place that restricts predatory fee practices, getting customers into revolving debt and protection that makes card issuers liable for purchases (Section 75 - e.g. if I order something paying with my credit card and the merchant doesn't pay, the card issuer is legally liable / I can claim from them and its on them to get it from the merchant)
