Paper doll is a small version of your character in the upper left corner that shows up when you're running or crouching... a welcome addition since my partner constantly crouches without realizing it only to be blasted by a creeper.
As for the monetization of the game, how else do you expect them to continue to support and develop a game that some people purchased as many as 5 years ago? It's either this or sequel after sequel after sequel like many other game studios would do. The fact that Minecraft is still going strong after so long from a development perspective is mind-boggling, and I just don't understand everyone whining about a company wanting to make money.
Also, if you don't like it, go play the Java Edition... it's not going anywhere yet and still has features that Bedrock doesn't, such as shields. The Java Edition has always been isolated... absolutely NOTHING has changed about the Java Edition. I'd honestly bet that the death of Java itself will be what kills the Java Edition... if you want to blame anyone, blame Notch for ever building the game on such a broken platform to begin with.
