 # Trade-offs of Using FOSS
 
 **Everything Comes with a Price:**
 
-
 * **Binary Limitations**: Proprietary formats like .docx not easily editable or human-readable in simple text editors
-  <!-- Longer: Proprietary formats like .docx are not easily editable or human-readable in simple text editors, unlike open formats -->
 * **Self-Responsibility**: No one to blame except yourself when things go sideways
 * **Accessibility Over Polish**: "Not so smooth" interfaces, therefore highly accessible  
 * **Modular Solutions**: Rarely "All-in-One"-Solutions, mostly a potpourri of multiple solutions to meet your needs
 * **Social Isolation**: Missing info/discrimination when avoiding mainstream platforms like WhatsApp/Instagram
-  <!-- Longer: Risk of missing information or being discriminated against when not using mainstream platforms like WhatsApp or Instagram, as others are locked into these communities -->
+
+<!-- 
+- .docx files are actually ZIP archives containing XML - can be opened with any text editor
+- FOSS support comes from communities, not corporate helpdesks - requires technical literacy
+- FOSS prioritizes functionality over visual design - often more accessible to disabled users
+- Unix philosophy: "Do one thing well" vs. proprietary "everything apps"
+- Network effects: harder to organize events, social groups when everyone else uses WhatsApp
