The section of people who care about anonymity has always been fairly small, even on niche communities like Hacker News. As an example, the most popular comment on the Australian social network ban for teens is in favour: https://news.ycombinator.com/item?id=46208348

Watching as things play out, I understand why people try to target discord et al. with their complaints about the loss of anonymity. Being a tiny minority they have no hope to influence their governments because the opposite position is widely popular.

Therefore, they try to convince commercial entities to disregard these laws as much as possible. This is particularly useful for that niche since fighting legislation cannot in itself be done anonymously. Therefore, they attempt to transform a very nonymous (haha) entity to do the fighting on their behalf. If the attempt fails, no harm befalls them.

I think it's a doomed endeavour. To get users on discord, it has to be portrayed to parents as a safe and legal service. The days of underground BBSes are gone. Now, if your brand gets associated with anything negative you're toast. And realistically the anonymous users are kind of useless as a whole. They won't pay, so they're practically just a drag on your platform. Losing them risks not very much.

Overall, a fight with a bygone conclusion. If you want anonymity you have to use other tools and be aware that simply using those tools marks you out as someone who desires anonymity.
