Where each one falls short

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

Line

  • Line has negligible market share outside Japan, Taiwan and Thailand, so it is the wrong choice for reaching contacts in most other regions.
  • A 2021 incident exposed that some user data had been accessible from servers operated in China, which led to a formal restructuring of data governance and remains a reference point for privacy sensitive users.
  • Standard chats are not end to end encrypted by default in the way Signal is; Letter Sealing, an opt-in encryption feature, has to be manually enabled per chat.
  • Business messaging through Official Accounts becomes expensive quickly once a company exceeds the free monthly message allowance and moves to a metered plan.
  • Ownership sits inside a SoftBank and Naver joint venture with a history of governance disputes between the two partners, which creates strategic uncertainty for enterprise customers relying on the platform long term.

Microsoft Teams

  • Resource-heavy application; slow to load and consumes significant CPU/memory compared to alternatives
  • Limited channel structure; maximum of 200 public and 30 private channels per team
  • Cannot invite guest users to specific channels; guest access grants full team visibility
  • Unable to chat during screen sharing; limits real-time collaborative communication
  • Limited customization options for branding and interface; cluttered UX compared to Slack
  • Channels cannot be moved between teams; requires manual replication for reorganization
