Oracle has a lot of money and lawyers, and how much of that have they used to actually protect the trademark? Do they sue people for infringement? Do they run ads in trade magazines saying, "hey please don't use our trademark generically"? How much money do they make from owning the trademark? Are they going to spend more than that to defend it?

if they dont do this, there wont be an opportunity for another case..

Well that is an urgency that Deno folks created. So it seems the deed is done.

You can't make this up. If I was Larry Ellison I would be calling Deno folks personally to thank them.

Exactly this. Poor judgement on the part of Deno's leaders.
