Someone should write a package that goes through your existing codebase to see which open source projects you make the most use of (however that is measured). Then a company could run it once a year, say around tax write off time, and build a list to donate to I would have happily given to log4j, but I didn't know that they were in need. Someone has to make it easy to keep track of this because it's never going to be…
Would millions of dollars of donations over the last decade have caused log4j to not have the vulnerability?
