Hi, I had a sleep on it. I thought about something. So, a few things about your responses made it clear you're not a native speaker of English - which is fine. I think I didn't consider the possibility that you're just using a word wrong. Based on your more detailed response, I don't think you consider Apple's service options "a joke". Here is an online definition of a joke (in this sense):
>informal
>a person or thing that is ridiculously inadequate.
>"public transport is a joke"
Perhaps I am wrong and you find it "ridiculously" inadequate, but from your comments it sounds more like you consider it sub-par or not competitive.
Let me think about if I can think of something Apple has done that's a joke. (I just Googled one.) So, the Apple III had no fan even though it needed one (engineers had miscalculated its heat profile) and as a result had a 100% failure rate. Its chips would melt out of their sockets.[1] One official solution to reseat the chips was to lift the machine 3 inches and drop it, to reseat the chips. This was in official company support documents.
That's a joke. (The story we're commenting under about failing keyboards might also qualify - but the support option itself doesn't seem to match this definition.)
Basically I think you're just using too harsh of a word for the options we're discussing - better words might be: lacking, inadequate, sub-par, etc.
