There was nothing wrong with any of the comments. We have been in the YouTube/Community game for long enough to just laugh at any "nasty" comments.. I've personally been involved here for the past 4 years. It really doesn't bother me.
You have to remember, at the end of the day, this is a business that has to pay for people to live and eat. Disabling comments and moving over to our platform is how we are managing to succeed and live off what other creators are shying away from. YouTube is no longer a successful business proposition for mid to large size channels. We have 230k subs, yet we're making pittance per view.
There is nothing but respect and love for our fans. We're on here constantly, we're proactive in our interaction in games and through discord. Heck, we're making multiple projects with the community and developing a game suited for them too.
I personally manage the social media and discord side of things, as well as some of the YouTube 'back end'. I find that point rather offensive, to be honest.
As for your last point, if you don't like Twitch, cool. Not forcing that on you. Many of our community are fine with it, some have been asking for it, and we have been on twitch for a few years now, so really, nothing has actually changed - there is just a lesser focus on YouTube's diabolical add revenue.
