No, it's not. Your religion doesn't affect how well your startup does, as you pointed out. This is just an unfortunate case of somebody using religion as a tool to sell you something you may not purchase otherwise.
I wouldn't build a christian startup because there is something magic about the christian label. It might even fail. It's about personally believing in the mission of Christ and wanting to share the love of Christ through your gifts and talents.
Also I will reach out to Slack's team to find out about the ToS. If this is truly the case then many other slack communities are in violation as well :/
Agreed. It is much more important to embody Christ in how you run your business - how you make decisions, and how treat your users, employees, partners, and investors without shouting it from the rooftops.
My wife recently gave me this quote from St. Francis - "Preach the gospel at all times, and when necessary, use words." I think it applies here.
I find it odd that someone would charge a fee to join a chat room. Doubly so if that chat room is meant as a way for like minded religious people to communicate.
Is there at least an animated collection plate that comes up during the sign up process?
In my opinion, you may want to drop the price tag on entry. It is widely looked down upon (eg — pay to pitch, etc) and will make you lose some credibility when it comes to discovering serious talent.
Also I feel bringing religion into business (which is essentially what startups are) is unwarranted. Don't get me wrong, but there is literally no correlation here.
You seem like a genuinely nice guy so I just dropped in my 2 cents, and yes, you should reach out to Slack. Best of luck, mate!
