Sure stuff in the past is good and all but tbh, people need to learn to accept change and be done with it. Minecraft is Mojang's game after all. Sure maybe we can give ideas and they might listen but saying "I dun liek this plz st0p upd8ting Min3craft lol" isn't giving good feedback :/
If people don't like the new textures then they can use a resource pack. I THINK we can't give out official textures in packs but if the textures change then the old ones aren't exactly official anymore right? If that theory is correct then someone will make a pre-1.13 texture pack. I personally like some of them but others...not so much, however I will give kind feedback and thoughts, unlike most companies, Mojang DOES listen to their players, even if its only a little.
People who want to live in pre-1.13 land or even in 1.8.9 land are free to do so, just remember that living in the past will make you miss out on the future.
You are basically forced. Considering some of the bugs in past versions that were corrected in later ones...
No you aren't. And most past versions weren't all that buggy -- at least not unplayably so (and the few that were usually had a lettered patch version released within a week or two correcting those specific bugs without any feature changes.)
But that's not even what I mean by "forced." Most games don't give you the option at all. You play the most recent update or you don't play at all (unless you're very highly technically literate and are capable of both finding and manually installing the files for older patches, as well as disabling the automatic updates so that your work isn't immediately undone as soon as you start the game up again.)
Even on Steam, where you can turn of autoupdates on a game-by-game basis you're only limited to two versions: The one you initially installed (if you disable updates) or the latest one (if they're on.) Its again rather difficult to choose a version in between those two (or older than your initial install,) and if you ever have to reinstall you lose access to the original one again.
