Look I really don't want to be a hater, but please look at the way your words are perceived publicly. This doesn't read as open comments about trademark law, it reads as defensive and oppositional.
This wasn't a huge PR challenge, all the statement needed to say was "Sorry, some lawyers we contracted applied for the trademarks in error, we have not progressed the applications and aren't claiming any ownership of the terms WASM or Webassembly".
Wasmer only has controversy because basic PR like this statement has been mishandled over and over again. You need to come off as good-faith actors participating in the WASM ecosystem. Defensiveness when you have obviously done the wrong thing, arguing with commenters under what is supposed to be an apology, employees posting supportive comments of their employer on said apology without disclosure... surely it is obvious how these actions are bad PR?
I know this reads really negatively but please understand that it's intended as sincere feedback. It's really important that Wasmer can reform it's image problem. There isn't any reason you guys should be perceived so negatively, if you can stop screwing up PR at every opportunity.
