Wasmer is considered a bad actor by many, and there are many in the WASM space who want nothing to do with them. It's no accident Wasmer isn't a part of the Bytecode Alliance [1].
A particularly damning incident was the time they tried and failed to trademark "WEBASSEMBLY", an open W3C standard [2] [3]. There are many choice words for companies trying these kinds of stunts.
Webassembly is growing despite Wasmer's existence. Not because of them. Be cautious.
Thanks for showcasing your concerns regarding the trademarks.
We created a public response to make sure those concerns are addressed. Hope this sheds some light:
