Your opinions on this are noted, but, largely, incorrect and misleading.
Just for future reference, Apple's product support areas supplies lots of info that you can find to help you with any of your Apple products.
It is up to the user to use due dilligence and do some research and take some responsibility about learning how to use and maintain/upgrade/update and generally take care of the Apple products you purchase and use.
Here is the Apple support document the takes you step by step through the Apple iDevice upgrade/update process found here.
Update the iOS software on your iPhone, iPad, or iPod touch - Apple Support
So, Apple DOES supply all of the info and support.
It is up to each user of an Apple product to avail themselves to actually look for the needed information first.
Also, if you ever downloaded any of Apple's iDevice users' guides, they always make references to Apple's user support section and technical support communities and help specialists.
I know all about Apple's support section, but All I did to find the info I needed quick was do a quick Internet search using the search terms iPad upgrade or iOS upgrade or update to find this Apple support document link.
Took me all of, perhaps, 20 seconds, or so, to find the appropriate document to help me avert any problems, diffuculties or data loss from happening on my Apple iDevice.
You, as the user, needs to take some responsibilty to find the proper info you need before just blindly doing something to your mobile devices that could potentially be detrimental.
