Twitter was not bad because "hashtags this" or "trends that". Twitter was bad because:
1. Centralized.
2. They forced you to ID yourself with a phone number.
3. They hand your data to third party companies.
4. Most governments were using it to ID people saying bad things about them.
5. Ads and corporative campaigns.
