I don't understand why I am forced to make an account. It seems to be purely for the purpose of selling me on a subscription service, which as far as I can tell, doesn't actually need to exist. Like who's going to pay an additional subscription on top of Slack or whatever they use right now? Is there any way to use this software without making an account?
