The authors largest bullet point is on author identification. What are the arguments against this and do people really feel they outweigh the benefits?

My view: I would think given how many code supply chain attacks we've see recently this would be be regarded as (at worst) a necessary evil. How much software used by large numbers of people does the open source community think will be done by anons?

Sidenote: The author implies SyncThing development was stopped due to author ID but the post linked does not say this and gives a completely different reason (forced updates)
