The Oracle Java SE support roadmap site says "extended support until December 2030". Will OpenJDK be covered under this support (i.e. security updates), or, is it it only available for paid support to OracleJDK?
OpenJDK 8 is maintained by RedHat. They will support Java 8 until 2026: https://access.redhat.com/articles/1299013
Most OpenJDK vendors will do the same. Some (like Azul) are committing to December 2030 like Oracle. You should check with your vendor.

Do you men adoptopenjdk? On their official page it states that Java 8 will be available at least till May 2026. It doesn't say anything about 2030.
Since they are different distributions I doubt that Oracle will make the Updates available for non paying customer.
Edit: the project moved to Adoptium...

More on reddit.comYes, it's still a LTS since extended support will be provided till 2030. You can check the official Oracle Java Roadmap.
For personal use, you can continue to get public updates from Oracle, but if you are a commercial user, make sure you have the commercial license if you want to use Oracle Java.
This is the reason that many commercial projects including my own rushed to switch to OpenJDK or Aws Corretto before the deadline to not violate Oracle's license. Fortunately, RedHat, which is main force behind OpenJDK communiy has committed to support OpenJDK Java 8 until 2026.
