Well, that page is about Oracle's binaries, not OpenJDK in general.
It's important not to confuse the two.

It may well be that Oracle don't provide public binaries of LTS releases,
but there's nothing stopping anyone else from doing so and I would
expect that to continue as it does now in various distributions.

The Oracle move seems to be explained by this comment:

"instead of relying on a pre-installed standalone JRE, we will begin
encouraging application developers to deliver JREs with their applications"

As Oracle move from adding their own magic sauce to create their proprietary
binaries to basically just building OpenJDK ("the ultimate goal is to make
OpenJDK and Oracle JDK builds completely interchangeable" [0]), the need for
them to do so at all diminishes as others can equally fulfil the role
("This will make it easier to publish early-access builds for features in
development,  and eventually make it possible for the OpenJDK Community itself
to publish authoritative builds of the JDK")
