We have very good reasons to distrust the virology community: Peter Daszak and the fact that he enjoys the support of that community.
-- He organized and signed the Lancet statement against the lab-leak theory, without disclosing his conflict of interest as a collaborator with the WIV.
-- He kept his EcoHealth Alliance 2018 proposal to insert furin cleavage sites into bat coronaviruses at the WIV secret, until it was leaked in 2021. A normal person would think it was obviously their moral duty to release any information potentially relevant to the origin of COVID. This alone made it clear Daszak cannot be trusted.
-- He has claimed that since the proposal was not funded, the work must not have been done. Every scientist knows that if you don't get funding from one source, you often pursue the work regardless.
-- A recent Senate hearing asked him whether he ever asked his collaborator Shi Zengli whether the work went ahead. He said he has never asked her. That's unbelievable unless he deliberately didn't want to know, in which case it's totally irresponsible.
The virology community and the NIH have closed ranks around this guy, so I don't trust them either.

Parsing WebAssembly modules does represent a small increase in attack surface, and there is additional attack surface if the browser has a dedicated WASM interpreter or JIT compiler. But in Firefox, for example, the WASM optimizing compiler uses the same Ionmonkey infrastructure as the JS engine so there isn't much new attack surface in that JIT compiler. That is very different from say Flash which had its own entirely different compiler.
WASM applications use the same browser APIs as JS does, so there is no new attack surface there. That's a big deal and one of the benefits of WASM's design over say (P)NaCl.
Overall, yeah, WASM adds some attack surface, but not much compared to the rest of the browser. And it's all contained in the sandboxed renderer process(es).
Stallman is 68 years old. He's had plenty of time to learn social graces with or without assistance.
If he is unable to interact appropriately with other people and unable to learn how, then we can have compassion on him, but he is poorly qualified to be on the board of a public-facing organisation.
