ESM
Questions about older versions still covered by ESM should be on topic on Ask Ubuntu.
There may be many valid reasons a person needs to use 14.04 or 16.04. Where else will they go to find an answer to there questions?
If Canonical can continue support of these versions, I think AU can find space to post these questions on this site.
Nobody is forced to answer these questions or to even view them.
Yes there was a phony vote to settle this matter earlier this year, something like 40 people out of a total of 25 million Ubuntu users voted to ban EoSS questions. This is far from a quorum.
