Will Microsoft ruin Minecraft?

I have been a Skype user for many years. At it's time there was nothing else like it. Did you know that you used to be able to share the same white board, have group conversations and even remotely access another computer? Everyone was all smiles and excited when Microsoft bought Skype. We didn't know at the time that MS would kill off all the cool features and functionality Skype users used to enjoy.
So now Microsoft owns it. Are they going to break it? Or even worse, change nothing at all? I'm betting on the latter. One thing that always made me feel good about Minecraft was the fact that it was always evolving and new things we're being added. I'm dreading this whole thing. Why are a few huge companies being allowed to buy everything? Doesn't everyone know it's a bad thing? When I was a kid there were literally thousands of successful game authoring companies. Now we're left with a few and very little variety in our choices. Because they want to make sure the games meet the widest possible audience, bringing slow death to many a gaming genera.Will Microsoft ruin Minecraft - 1

Is it near to impossible to become big on YouTube now?

What I mean by this is although there's of course big channels out there, those channels normally started off a couple of years ago.
Is it all down to content or because of the big channel (seananners, goldglove ect.) making more people believe they can do the same, therefore more people making videos.
So is it down to good content, starting off a while ago (or just dodgy thumbnails)
Thanks.
