Commercial support for Python 2 will probably continue for a while, in
the same way that support for versions older than 2.7 is still
available to Red Hat customers today (if I'm not mistaken). Otherwise,
well, the software will continue without updates or security patches
until it breaks. Companies will have to weigh up five costs against
each other:

1) The cost of the status quo: the risk of critical failures or
external attacks against unsupported and unpatched software

2) The cost of migrating to Python 3

3) The cost of migrating to a completely different language

4) The cost of maintaining their own local fork of Python 2

5) The cost of using a supported commercial platform such as RHEL.

For most small to medium projects, it's probably going to come down to
#1 or #2, where #1 has the laziness bonus. For many larger companies,
#1 is an unpayable cost. Everyone has to make that choice, and
remember that "cost" doesn't just mean money (for instance, the cost
of moving to Linux might be quite considerable for a Windows shop, and
even within a Linux ecosystem, switching to Red Hat may have
consequences to other programs you might need).
