This was discussed over on /r/java when it came out. The tl;dr is that it’s a poorly worded blog post about the OracleJdk (the one you pay and subscribe to). Graal isn’t going anywhere.
Auditing is only for paying customers of commercial products who've agreed to it in their contract. There's obviously nothing to pay for because the JDK is free. Oracle doesn't even collect contact information when downloading the JDK.
What could be happening there is that an Oracle customer uses their customer account to get access to a non-free JDK, such as an update that isn't offered on the public website because it's past the free update period.
