As @deathmetal27@lemmy.world answered, and adding my personal answer, personally I didn't see any problem by using Amazon Corretto.

Currently, there are no contracts nor paid licenses by using Amazon Corretto in commercial use and even in enterprise environment. Nothing, just use it. Compared with Oracle Java SE where if you use it in commercial purpose, Oracle may caught and demand you to pay.

And I spent some of times in AWS too, and I felt, using dual JDK's builds (Corretto for work, and another builds (let say Temurin or Zulu) for personal) is still kinda inefficient. This is the reason of why I stick to Amazon Corretto.

But, if you didn't using AWS and/or didn't like Amazon in general, nobody can force and stop you, there are alternatives, and you can use Temurin, Zulu, or Liberica.
