I didn't say it was.

I did not contend that either.

This I disagree with - the license choice is not incidental; it is foundational to gain popularity in a hurry, to gain widespread adoption at corporates.
The rewriter's intentions is to gain popularity over the incumbent software; using a pro-user license does not gain popularity for all those pro-business use-cases.
The license switch from pro-user to pro-business is not incidental. It's deliberate, and it's too achieve the stated goal of replacing the existing software.
This is one place where I feel that the ends do not justify the means.
