My interpretation of the grandparents comment is the $6B in revenue (probably from outside Ireland) would not be subject to the 20% tax, while they are subject to 1% tax. So by raising taxes to 20%, you lose all foreign companies like Uber paying 1%, which may very well add up to much more than purely revenue originating within Ireland. I could be completely wrong, I’m not a tax lawyer
