Unjustifiable assertion.

  - they could continue to maintain python2
  - they could move to a non-python platform
  - they could go out of business
  - they could hold out for Python4 (Python3 was only 8 years after Python2)

GVR has already said that Python 4 (if it's even ever called that) will not have the same kind of breaking changes 3 did.

And 3 had different changes than 2 (https://docs.python.org/3/whatsnew/2.0.html) though it is interesting that Unicode support was a big feature in both, and that many people still find Python3’s Unicode support problematic (e.g., http://lucumr.pocoo.org/2014/5/12/everything-about-unicode/)

But if an individual or organization does not find the python 3 updates and ecosystem a compelling upgrade over 2, “don’t update until the next big change” is definitely one option.

The whole point of my comment is that there won't be a "next big change", just lots of smaller ones.
