I've used https://www.enchant.com/ for two small companies over the last decade, and have been happy with them. Cheaper than Zendesk, and just much simpler to use.
It would be great if YouTube let creators pay for hosting directly (just like other web hosts) if they wanted to maintain the ad-free experience for their viewers.
Steam has its own set of issues where they control what you get to play, and when.
I feel like I've "bought" a ton of games through Steam, and now that my kids are a bit older, they want to play some of them. Unfortunately they can't play different games at the same time - even with Steam's family sharing. When one person plays a game, it locks the whole game library.
