Sure, but it will still negatively affect the number of users.

For example, I'm already aware of one community that decided to end their IRC presence altogether (and only keep their discord) rather than migrate their freenode channel to another network.

There will undoubtedly also be a number of individuals who decide to just quit IRC instead of moving.
