You don't then get to go and complain that the community isn't treating you well. They're right not to trust you.
You use Oracle's JS trademark as precedent, but that's woefully ignorant of how it came about. JavaScript was not a four year old open standard when Oracle came along and scooped it up. JS was a Java branding deal between Sun and Netscape.
If you want to contribute to build something good, because a strong wasm community is in your best interest, drop the attitude and don't make any more moves to sabotage the project.
If you want to lawyer up and try to exploit the fruits of the community, then do that. But you need to pick a lane. I don't see Larry hanging around HN complaining about how people are treating him on GitHub.
I don't have a dog in this fight. Prior to this thread, I didn't know about you, your company, or anyone in all these links you've posted except I remember reading a post by Lin Clark once.
I wrote another post that I deleted pretty quickly when I realized how aggressive it sounded. But it wasn't trying to be aggressive, just convey the hostility of what you did and how you should expect people to react.
