As someone pointed out in that thread, there's also an HN account that appears to be a sockpuppet of the CEO[1], used to astroturf his projects (wasmer and a previous one).
For me, finding that was one of the things that made me pick wasmtime over wasmer for my own project.
8 months ago I was evaluating Wasmer vs. wasmtime for my personal use and for a team I was working with at my work (Sourcegraph)
Ultimately I went with wasmtime (we ended up using neither at work, too premature) because I just found a frankly disturbing amount of controversy surrounding Wasmer vs. wasmtime, and Wasmer hyping itself up far too much and trying to put down wasmtime.
I'll say as I did 3 months ago[0]. I don't know what's wrong with Wasmer, but there's something _weird_ going on there. I'm not surprised to see this thread.
