Zoho prices strategically. For example, it ensures that the price for the help desk product, ZohoDesk is the lowest in the market; across all tier it is priced at USD 1/month cheaper than the next cheapest competitor, FreshDesk.
They just separated out Servers in Endpoint Central, where servers now require a different license. My use of the product will not change, the price of renewal goes up 12%. I'm paying more this year for the same thing. Strategic pricing indeed, lock'em in and crank'em up.
Also, Redhat and CentOS are 'servers' under this new licensing, but Ubuntu is not a server.
I've found Endpoint Central to be rather buggy, and not really improving over time, they just keep introducing new bugs.
