Ubuntu makes this worse by using "end-of-life" dates as End-of-ESM at various pages[0,1]. If you read that page, you'll assume all packages will be supported till EOL for all users. This is all it says about ESM:

The Pro page[2], now has a clear graphic comparing the security coverage, but this appears to be new.
