It is highly unlikely and near impossible that we will have any impact on your business with Siteocity. We taking on limited signups and the client base will be no more than 1,000 customer at any given time.I don't think it's a good idea for cPanel to go into webhosting business - even for direct knowledge.
People now will want to host with cPanel because they need cPanel server, so they'll come directly to you instead of choosing me. That will make me cancel few of my cPanel licenses because I am losing customers.
Anyway, I think you should have trusted us (your customers) more. You have great forums and had (past time) great tickets support team, that means you have enough info about what should be fixed and what features we need. If we say for example that we need cpu/ram limit - we need cpu/ram ability to limit our users. You will see you need that too now with your webhosting company, but you should have trusted us more.
What is next, WHMCS starting webhosting business just so they have direct experience about their software usage?
Sell the company.
We have tons of data from various sources, including tickets, forums, meetings with hosting providers, and in rolling out new features this will provide us another way to validate and understand it a little better.
We certainly respect your opinion on the matter and I would like to note, that our intentions have been both forthcoming and honest. We have no aspirations of being a hosting provider.
