My opinion as well as many as my peers is that ACF could have been rolled into core or bought by Matt long long before it was acquired by WPE, which most of us found as a good thing, being that its a critical plugin and gained long term support.

Plugins have bumps, that's part of the growth, and some of the changes ACF have made as of recent years, even the ones I disagree with, seem well intentioned and not malicious. I can't say the same for what is happening right now.
