Agreed, but I think the point was that the user has a workaround. Use a standard browser for the like five minutes it might take to unsubscribe from these mailing lists, a one-time operation per business, done.

If on the other hand unsubscribing from mailing lists is not the true use case and we are actually being asked to help a bot bypass safeguards… then Cloudflare is doing a great job here.
