I keep trotting this comment out every few weeks, because it happens so often now that the cloud eats something we own. Probably my most frustrating experience was when Apple forced me to update iOS, but they removed many features that I relied on. BTSync broke, Nightshift functionality that I was using with Flux was rendered unusable. And a ton of other little annoyances[1].
Apple heavily damaged my iPad with an update awhile ago. And Apple won't take no for an answer, and will keep downloading the next iOS update even over a cellular connection, so I had to firewall it.
Computing today might seem seamless, but, just you try and go against the grain. You'll encounter a remarkable amount of resistance. All I want is so have agency over the devices that I buy.
Preventing or no longer supporting access to media should be similar and require an alternative format be made available, so Amazon can block access to an ebook or movie but must provide a download instead.
That would balance alittle the current disparity of power the companies hold IMO.
Recently NowTV/Roku unlawfully accessed my set-top box and disabled an app, the main reason for having the device, because they don't like it. They claim it's illegal but it's available from the curated app-store if I buy the more expensive device from the same manufacturer (or indeed a device from many other manufacturers).
I can't afford a lawsuit and we don't have group actions in the UK. Net effect a company cripples a device because they don't like how it is being used, and commit unauthorised access of a computer system in the process (currently illegal, but only individuals are being prosecuted for it).
We need protection from such companies.
