I've found that, in general, the tooling hasn't changed much _because_ of the acquisition (for the Java edition). It's mostly been down to the developers working on such tools maturing and producing better software, not to mention larger companies like Twitch/Curse producing their own stuff as well. I can't speak much for the Bedrock edition community (Windows 10/Console/Mobile versions) since it's a very different beast, but the Java side of things is still alive and well. I'm not sure if I can comment on the popularity of larger for profit servers, but from my casual observation they seem to have taken a slight hit in terms of player numbers.
