Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Karabiner-Elements

  • It requires granting significant system-level permissions, including input monitoring, which some security-conscious users are reluctant to allow.
  • Writing custom complex modification rules by hand means editing JSON, which is a real barrier for a non-technical user without the community rule library.
  • It only remaps keyboard input, so a user who also wants gesture or window management customisation needs a second tool such as BetterTouchTool or Rectangle.
  • Being an unpaid open source project, support depends on GitHub issues and community forums rather than a vendor support desk with guaranteed response times.
  • It is Mac only, so it does nothing for remapping needs on a Windows or Linux machine in the same household.

Starbucks

  • Loading a prepaid balance onto the app effectively lends Starbucks money interest-free until it is spent, and Starbucks has reported billions of dollars in unredeemed stored value outstanding at any time.
  • Mobile order pickup often creates its own bottleneck at busy stores, so the convenience of skipping the register queue can be offset by waiting at the pickup counter instead.
  • Rewards redemption values and item eligibility change periodically, so accumulated Stars do not have a fixed, predictable cash value over time.
  • The app collects detailed purchase history to power targeted offers, which is the trade for the free loyalty programme rather than a neutral convenience feature.
  • Auto-reload linked to a card can catch users off guard with unexpected small recurring charges if they are not tracking their balance.

Answered from the vendors’ own pages

Karabiner-Elements: Is Karabiner-Elements really free?

Yes, entirely. It is open source under the MIT licence with no paid tier, though the project accepts voluntary donations.

Starbucks: Does it cost anything to join Starbucks Rewards?

No, joining and using the app is free; you pay only for what you order.

Karabiner-Elements: Does it work on Apple Silicon Macs?

Yes, versions from 14 onward run natively on M1 through M4 chips.

Starbucks: What happens to money loaded onto the app if I stop using Starbucks?

It remains as a stored balance unless redeemed; Starbucks does not pay interest on it and, subject to local law, unredeemed balances can eventually be treated as breakage revenue.

Karabiner-Elements: Do I need to write JSON to use it?

Not necessarily. Simple key swaps use a GUI, and complex modifications can be imported from a public community rule library instead of writing rules by hand.

Starbucks: Can I pay without preloading a balance?

Yes, many stores accept direct card or contactless payment without using the app's stored value feature.
