There is zero chance the author of that issue read their own post.

The vast majority of license violations are just MIT or ASL projects whose license text got stripped in the minified deliverable. Just adding source maps for those libraries is enough to become compliant.

I have no clue with regards to LGPL on the web but since it is delivered via WASM, there is a linking boundary so it might just be an issue regarding letting users bring their own implementation.
