I could deal with the other problems from this update, but to me the biggest issue was stuffing in the onpage.org check with no way to disable it. This was clearly a violation of the WordPress plugin rules about phoning home (#7) https://wordpress.org/plugins/about/guidelines/

The last update did add a way to disable, however it is still turned on by default.

That was obviously not well thought out nor well implemented. A simple disable option would have prevented a TON of issues in the first few 3.0 releases.
