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.

Yelp

  • Its revenue model depends on selling advertising and leads to the same businesses being reviewed, which creates a structural tension over how neutral rankings and filtered reviews really are.
  • Businesses can pay to have a competitor's ad appear on their own listing page, a practice that has drawn sustained criticism from small business owners.
  • Yelp's review filtering algorithm is not disclosed in detail, so businesses cannot audit why some reviews are filtered out as unreliable and others are not.
  • Review quality varies widely by category and city, with restaurants and nightlife much better covered than niche trades in smaller markets.
  • Consumer data such as searches and saved lists feeds Yelp's advertising and lead products sold to businesses, which is the actual monetisation even though the app itself is free.
