Ubtu = Ubuntu
Trisquelize = Transform Ubuntu into Trisquel. Now, it would be, to take the
control over Ubuntu to make it Software Libre, step by step.
There is a script to older versions that transform Ubuntu to Trisquel.
trisquelize.sh:
https://trisquel.info/es/wiki/migrar-de-ubuntu-trisquel-sin-reinstalar
If it is not possible to update that script to completely liberate Ubuntu
now, I am suggesting the script prepare Ubuntu to accept Software Libre by
the user (right now), and then, every step to make it libre will be installed
every time developers of Trisquel has it ready.
Configure Ubuntu to trisquelize it step by step developers require. Instead
of releasing whole Trisquel with all the liberation done.
