Looking at Wikipedia now, nothing this article says is accurate... Search the page for "two consecutive" it appears 6 times.

Look, I strongly dislike changing definitions for things as a result of one political party or another - but this concern re wikipedia is manufactured I think.

The wiki article on recession literally mentions two consecutive quarters of negative growth: https://en.wikipedia.org/wiki/Recession

The history page even goes into whats going on behind the scenes with vandalism and the like: https://en.wikipedia.org/wiki/Talk:Recession#ATTENTION_NEW_V...

Not to say that we shouldn't deride the changing definition in popular media, but wikipedia seems fine ?

From paragraph 2 of the wikipedia article: "Although the definition of a recession varies between different countries and scholars, two consecutive quarters of decline in a country's real gross domestic product is commonly used as a practical definition of a recession"

As for locking the page, this is a common (and prudent) measure whenever a page suddenly becomes "hot" politically.
