Microsoft users switch for Office integration. Gain: M365 included, cross-platform. Trade-off: Microsoft ecosystem lock-in.

Users concerned about Apple's compliance with US surveillance laws switch for Swiss-based privacy protection. End-to-end encryption by default. Part of the Proton ecosystem with Mail, VPN, and Calendar.
