if it was possible to challenge Bloomberg, many wallstreet companies, banks, hedge funds would've done it already. the fact is they remain a moat. horrible ui but fast news reporters that the industry relies on. this is not something open source can fix (never was the issue), it is about hiring dozens of financial journalists who quickly deliver news
Note that the terminal typically shows news headlines and stories before they are posted to the public internet.
As long as Bloomberg publishes their own articles that "move markets" there will be value in being able to see those articles before the rest of the world.
