This happens every update:
1.7: "MINECRAFT IS RUINED!11!! 1.7 is horrible!!!!!"
1.8: "Mincraft is ded!!! PVP is RUINED!"
etc...
If you pay close attention to the updates, you will see that the PVP changes now require a lot more skill to master. Currently, if you can click fast, you can win. These new mechanisms add more skill to the game.
I agree that it will take some getting used to, as does any update. When the new stained clays came out, nobody liked them. Look now, everyone loves building with them.
As for your comment about Microsoft; they have nothing to do with any changes made to the game. There has been no new developers added to the Mojang team since the acquisition. Any changes made to the game are purely of what the developers and Mojang team think players would like.
It's not possible that any server won't update to 1.9, every server must update. Servers can't sit in a 1.7 / 1.8 protocol hack server forever, just because there are a few people who dislike it. when 1.10 comes out, we will still be sitting on a 1.7/1.8 server, which would be a nightmare for developers, having to upgrade so many things all at once. The developers can choose not to add potion arrows, or any of the new items that you dislike.
