I have my own prejudices. I'm a person who still uses POP mail because I want all my email stored on my own freaking computer, because putting something important on someone else's server, insead of evoking confidence and security, fills me with unease. Paid professional services as well as free ones yank resources out from under you or change policy on a dime. Things that were included as part of what you were paying for get discontinued by unilateral decision and you have to migrate all your stuff or frantically rescue it to your hard disk. Or it gets hacked. Or they change the protocols in a way that breaks all your carefully designed applications, informing you of this in an email off of which the smell of self-congratulatory pride is annoyingly wafting.
It's not that I've always advised all my clients to buy a server, learn how to maintain it in a temperature-controlled and electrically redundant safe room, and host their own FileMaker solutions on their own copy of FileMaker Server. Although I've done that often, I've also recommended reliable hosting companies. Usually ones that, in addition to being well-established as Filemaker-centric and to not stretch their capabilities too thin, and to having responsive tech support, also have the advantages of letting you upload with mainstream tools instead of propretary web interfaces, that let you manage FmServer with the regular FmServer console interface and not some stripped-down simplified version, that don't impose a lot of "my way or the highway" / one-rule-fits-all template stuff and lets the client implement their solution as they wish.
My early experience of Mac versus PC is directly contrary to the legend of Apple being closed and PCs being open: in a world where PC programs couldn't give you choices, early Mac apps were chock-full of options, and in a world where DOS and Windows users were terrified of downloading anything new for fear of DLL conflicts or viruses, we Mac users changed the default behaviors of the OS to fit our liking with shareware and freeware quite fearlessly. But yeah, there's no denying that Apple has some heavy-handed attitudes and an annoying fondness for abstracting the real situation and representing it to end users in babytalk.
Their version of 'Cloud' extends that far beyond merely promotiong 'We will house your creations on OUR server' as this mystical mythological Cloud thing (which they're all guilty of).
