As many have pointed out, you can argue if this is a trap or not and you can make the case for both sides. But I think that discussion in itself clearly begs the question: do you want to deal with a company that makes it easy to make a potentially immensely expensive mistake?

If anything, Oracle have demonstrated that if they feel you owe them something, they will take you to court.

I changed what primary programming language I use as a conscious decision that took years to make. First I had to find a language that was a good replacement and then I had to make the switch. Both require care.

It was easier than I had thought though. And I'm very happy I did.

Am I sure the my new primary language won't grow these problems? No. But I do know that I'd do it again if needed. There is no shortage of programming languages. There is a shortage of programming languages that have a sufficiently good ecosystem around them though.
