Because it can't.

The bitcoin github and subreddit were taken over by a group of people that just wanted to make a centralized second layer that they could sell. They used (and still use) lies, propaganda and heavy censorship to keep the transaction capacity at only a few per second. Floods of incoming people that had no in depth understanding were and still are unaware that /r/bitcoin was like /r/thedonald - anything (even questions) against the (technically ridiculous) propaganda message that more than a few kilobytes per second in transactions would be a disaster was deleted and the user was banned or shadow banned.

This is not controversial, you can still check out /r/bitcoin

Cryptocurrency in general is an idea whose time has come. Electronic currency that can be used without permission from a third party has many enormous advantages. The original bitcoin chain is nonsense and has been a disaster for the last 7 years.
