- Funding scrutiny:
- Signal has faced questions about its funding sources, particularly its ties to the U.S. government in its early stages.
- This has led to debates about potential conflicts between privacy goals and government interests.
- Pressure on app stores:
- Some governments have pressured app stores to remove Signal and similar apps, citing national security concerns.
- Criticism of metadata collection:
- While Signal collects minimal metadata, some privacy advocates argue that even this limited data could be vulnerable to subpoenas or hacks.
Despite these challenges, Signal has generally maintained its stance on strong encryption and minimal data collection. The company continues to advocate for user privacy, often engaging in public debates and legal battles to defend its position.
