1) apple has popularized the GUI, the touch screen, the smart phone, the form factor for pretty much every laptop sold today (look at the first PowerBook, then look at all Windows laptops before it). Apple has given us volume controls on the headphone line - yes, the same tech that people bitch that apple will pull, Apple finally made super useful with volume and logic controls. I go nuts with headphones that don't have these controls - a non-ironic Thanks Apple here.
2) apple has given us the 3.5 inch floppy, then removed it. It gave us the first easy to use networking (Appletalk over LocalTalk, or more likely PhoneNet) then removed it for TCP/IP Rendezvous/Bonjour. It has essentially removed all CDs from it's devices, so it gave us iTunes to rip CDs, now no CD player to rip from. It dropped the Motorola 68000, then dropped PowerPC.
3) It's not even the first jack free phone - motorola beat them to it, with a phone that (sadly - Motorola was once a Lion) no one will buy so Apple will be seen as the first.
So, Apple regularly adds and/or removes tech. It's part of their DNA. They've radically moved computing forward and sometimes they're the first to cut ties to an old past. Whether you like them removing it or not, doesn't mean it's a "hey they're GREEDY" everytime they change something. Remember that soon, your iOS9 phone will become an iOS10 phone and do more things. They're not charging you for that. For free, your mac will do more new things. The headphone jack is long, the headphone jack is thick, and the headphone jack makes it harder to waterproof. Why is everyone complaining? because bluetooth headphones suck. Well, here's Apple designing a future to make them suck less.
